F(x)=x^2 what is g(x) (1 9) brainly- Explanation The value under a square root cannot be negative, or else the solution is imaginary So, we need 9 −x2 ≥ 0, or 9 ≥ x2, so x ≤ 3 and x ≥ − 3, or −33 As x takes on these values, we see that the smallest value of the range is 0, or when x = ± 3 (so √9 − 9 = √0 = 0 ), and a max when x = 0, where y = √9 − 0Create your account View this answer Given f(x) =2x1 g(x) =x2 f ( x) = 2 x 1 g ( x) = x 2 Recall that fog= f(g(x)) f o g = f ( g ( x)) f(x) = 2x1 f(x2) = 2x21 f ( x) = 2 x 1 f ( x 2
Then, f(x)g(x) = 4x 2 4x 1 = 1 Thus deg( f ⋅ g ) = 0 which is not greater than the degrees of f and g (which each had degree 1) Since the norm function is not defined for the zero element of the ring, we consider the degree of the polynomial f ( x ) = 0 to also be undefined so that it follows the rules of a norm in a Euclidean domainG ( x ) = \frac { 1 } { x ^ { 2 } ( 1 x ) } g(x) = x2(1 − x)1 Use the distributive property to multiply x^ {2} by 1x Use the distributive property to multiply x2 by 1− x \frac {1} {x^ {2}x^ {3}} x2 − x31Start your free trial In partnership with You are being redirected to Course Hero I

Let's rephrase the question to have less confusion about the used variable > What does mathf(q)/math equal to if mathf(q^2) = 9/math? Explanation The problem with this type of question is often the confusion that results from two different uses of x If instead we write XXXf (w) = w2 −w then there is less difficulty in replacing w with g(x) XXXf (g(x)) = g(x)2 − g(x) and then replacing g(x) with 3x 1 XXXf (g(x)) = (3x 1)2 − (3x 1)Graph f (x)=9 f (x) = 9 f ( x) = 9 Rewrite the function as an equation y = 9 y = 9 Use the slopeintercept form to find the slope and yintercept Tap for more steps The slopeintercept form is y = m x b y = m x b, where m m is the slope and b b is the yintercept y = m x b y = m x b Find the values of m m and b b using the

We are given two separate functions, namely f(x) and g(x) Since f(x) is a difference of two squares (x^2 is a squared term and 81 is a squared term), we can rewrite it as (x 9)(x 9) Now, this will help us when we multiply through by g(x) Let's discuss the solution to g(x) In exponent laws, any number to the power of a negative numberFind f(g(x)) f(x)=x^29 , g(x)=3x, Set up the composite result function Evaluate by substituting in the value of into Simplify each term Tap for more steps Rewrite as Expand using the FOIL Method Tap for more steps Apply the distributive property Apply the distributive property Apply the distributive property Simplify and combine like terms Tap for more steps Simplify each If f (x)=1x and f (1x)=1 (1x)=x, then they are not the same Thus, it's not the right answer I would pick number on this question A 13=2, 1 (2)=3 Not the same B 1 (3)^2=8, 1 (2)^2=3 Not the same D (3)^2 (13)^2=9*4=36, (2)^2 (12)^2=4*9=36, Same answer
Solution Steps Factor out x Factor out x Consider x^ {3}3x^ {2}x3 Do the grouping x^ {3}3x^ {2}x3=\left (x^ {3}3x^ {2}\right)\left (x3\right), and factor out x^ {2} in the first and 1 in the second group Consider x3 3x2 −x− 3 Do the grouping x3 3x2 − x− 3 = (x3 3x2)(−x−3), and factor out x2 in the first and f (x) = (2 −x1 2) and g(x) = x2 − 9 so, g(x) ÷ f (x) = x2 −9 2 − x1 2 Now, the denominator cannot be zero ie 2 − x1 2 ≠ 0 so, x1 2 ≠ 2 Hence, x ≠ 4 Therefore, the domain is all values except x = 4 )>G(x) → "g of x" → "operation(s), g, applied to a given quantity or value , x" "g(x) = x1" tells you to simply subtract 1 from whatever xvalue is given g(5)= 5–1=4 g(6)= 6–1=5 g(9)= 9–1=8 g(x)=x1 f(x) → "f of x" → "operations, f, applied to a g
In this question you therefore replace the x in 2x4 with x 2 1 This leads to g(f(x))=2(f(x))4, or g(f(x))=2(x 2 1)4 The next step is to expand the brackets, giving 2x 2 24, and then to collect like terms to give g(f(x))=2x 2 6 Answered by Georgina M • Maths tutor 387 Views See similar Maths GCSE tutors Need help with Maths?One to one online tuition can be a great way toWhich simplifies to −1/x 2 Multiplication by constant Example What is ddx 5x 3 ?For example, if we apply the function f to f(x), we have ff(x) or f 2 (x) f 2 (x) = ff(x) = f(x 3) = (x 3) 3 = x 9 One thing to note when calculating composite functions is that fg(x) is unlikely to be the same as gf(x) For instance, from using f(x) and g(x) from our example above, we can calculate gf(x
