Pleasee hel mee

here is the picture

Answer 1

7/2, 1

Explanation:

g(h(x)) = g (2x - 7)

=
`x^(2)` - 1 (2x - 7)

= 2x³ - 7x² -2x +7

= 2x³ - 2x - 7x² + 7

=2x (x² - 1) -7 (x² - 1)

= (2x - 7) (x² - 1)

thus, the two possible values of x are,

7/2, 1

Answer 2

Okay, let’s do some math. To perform the indicated operation, we need to substitute h(x) into g(x) and simplify. That is:

g(h(x)) = g(2x - 7)

= (2x - 7)² - 1

= 4x² - 28x + 49 - 1

= 4x² - 28x + 48

The final answer is 4x² - 28x + 48.
