Evaluate f ( - 6) for the function f (x) = 4 (x + 2) + 13.

f (x) = -3

f (-6) = -3

Step-by-step explanation:

We want to find f (x), or y, when x is equal to - 6. To do this, substitute - 6 in for x.

f (x) = 4 (x + 2) + 13

f (-6) = 4 (-6 + 2) + 13

Solve inside the parentheses

f (-6) = 4 (-6 + 2) + 13

f (-6) = 4 (-4) + 13

Multiply 4 and - 4

f (-6) = - 16 + 13

Add - 16 and 13

f (-6) = - 3
