Answer:
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
