Answer 1

$h(x) = x^{2} -5$

Since x is equal to -7, substitute all the x's with -7.

$h(-7) = -7^{2} -5$

$Parentheses \\ Exponents \\ Multiplication \\ Division \\ Addition \\ Subtraction$

Exponents is first:

$-7^{2} = -7 \times -7 = 49$

Your new equation is:

$49-5$

Subtract:

$49 - 5 = 44$

Your answer is:

$h(-7) = \bf 44$
