Question

For the function h(x)=−4x−72, what is the value of

h(15)?
a) -132
b) -120
c) -12
d) 48

Answer 1

(15, -132) is the answer

Answer 2

By substituting 15 into the function h(x) = -4x - 72, we calculate h(15) = -60 - 72, which equals -132. Therefore, the correct answer is option a) -132.

Step-by-step explanation:

To find the value of h(15) for the function h(x) = -4x - 72, we simply substitute 15 for x in the function and then perform the arithmetic:

h(15) = -4(15) - 72

h(15) = -60 - 72

h(15) = -132

So, the value of h(15) is -132, which means the correct answer is option a).
