What is the inverse of function f? F(X) = square root of x +7

katrin2010 [14]

Answer: $f^{-1} (x)=x^{2} -7$

Step-by-step explanation:

To find the inverse of a function replace f(x) with x and the original x with y

$f(x)=\sqrt{x+7} \\x=\sqrt{y+7}$

Now we can solve for y

Square both sides so we can cancel out the root

$x=\sqrt{y+7}\\x^{2} =\sqrt{y+7}^{2} \\x^{2} =y+7$

Now subtract 7 from both sides

$x^{2} =y+7\\x^{2} -7=y+7-7\\x^{2} -7=y$

Now replace y with the inverse of f(x), $f^{-1} (x)$

Given two functions f(x) and g(x): f(x)=4x^2+2, g(x)=3x+2 form a composition g(f(x))

9966 [12]

G(f(x)) = g ( 4x^2+2) = 3 (4x^2+2)+2
= 12x^2+6+2 = 12x^2+8
