Question

Lf f(x) = 2(x - 5), find f(8).

Answer 1

f(8)=6

Explanation:

plug in 8 for every x value. With this knowledge, the new equation would be f(8)=2(8-5)

then, simply solve it

f(8)=2(3)

f(8)=6

Answer 2

f(8) = 6

Explanation:

Just plug in x=8

f(x) = 2(x - 5)

f(8) = 2(8 - 5)

f(8) = 2(3)

f(8) = 6
