Question

Given the function f described by f(z) = -22 + 5z - 2, find the function value f(-6):

A) f(-6) = -54
B) f(-6) = -64
C) f(-6) = 4
D) f(-6) = -4

Answer 1

To find the function value f(-6), substitute -6 for z in the given function f(z) and simplify the expression.

Step-by-step explanation:

To find the function value f(-6), we substitute -6 for z in the function f(z). So we have:

f(-6) = -22 + 5(-6) - 2
= -22 - 30 - 2
= -54.

Therefore, the correct answer is A) f(-6) = -54.
