Studdy Solution

STEP 1

1. We are given the linear function f(x)=−11x−10 f(x) = -11x - 10 .
2. We need to evaluate this function at x=−8 x = -8 .

STEP 2

1. Substitute x=−8 x = -8 into the function f(x) f(x) .
2. Simplify the expression to find f(−8) f(-8) .

STEP 3

Substitute x=−8 x = -8 into the function:
f(−8)=−11(−8)−10 f(-8) = -11(-8) - 10

STEP 4

Simplify the expression:
f(−8)=88−10 f(-8) = 88 - 10

STEP 5

Continue simplifying:
f(−8)=78 f(-8) = 78
The value of f(−8) f(-8) is:
78 \boxed{78}
