If f(x) = 2x + 10, then f^-1(x) =

Nady [450]

If $f^{-1}(x)$ is the inverse of $f(x)$ , then

$f\left(f^{-1}(x)\right) = x$

by definition of inverse function. We have

$f\left(f^{-1}(x)\right) = 2f^{-1}(x) + 10 = x$

Solve for the inverse :

$2f^{-1}(x) + 10 = x \\\\ 2f^{-1}(x) = x-10 \\\\ \boxed{f^{-1}(x) = \dfrac{x-10}2}$

The difference of $(8x^2 + 9) - (6x^2 + 2x+2)$ is $=2x^2-2x+7$

Option B is correct.

Step-by-step explanation:

We need to find the difference of $(8x^2 + 9) - (6x^2 + 2x+2)$

Solving:

$(8x^2 + 9) - (6x^2 + 2x+2)$

Multiplying - sign with terms inside the bracket

$=8x^2+9-6x^2-2x-2$

Combining like terms

$=8x^2-6x^2-2x+9-2$

$=2x^2-2x+7$

So, the difference of $(8x^2 + 9) - (6x^2 + 2x+2)$ is $=2x^2-2x+7$

Option B is correct.
