Answer:
h (-7) = 44
Step-by-step explanation:
when working with a function, when we place a value, replacing x, in parentheses next to the function, we are to find the function by replacing x with that value.
Essentially, we need to replace x with -7. [replace meaning substitute]
h (x) = x² - 5
h (-7) = (-7)² - 5
h (-7) = 49 - 5
h (-7) = 44
so, h (-7) = 44
note: ² means to square a number (to multiply that number by itself)
(-7)² -> - 7 · - 7 = 49
