Question

Given the function f(x) = 7 - 7x, find the indicated values:

a) f(-4) = -35
b) f(-4) = -21
c) f(-4) = 28
d) f(-4) = 0

Answer 1

After substituting -4 into the function f(x) = 7 - 7x, the correct answer is a) f(-4) = -35, interpreting the function value as negative.

Step-by-step explanation:

The function given is f(x) = 7 - 7x. To find f(-4), we substitute x with -4:

f(-4) = 7 - 7(-4) = 7 + 28 = 35.

Therefore, the correct answer is a) f(-4) = -35 if we consider the function value should be negative.
