Question

Find the function value, if possible. (If an answer is undefined, enter UNDEFINED.)

f(x) = 3x - 4
f(x + 2)

Answer 1

f(x + 2) = 3x + 2

Explanation:

Simply replace wherever you find x in the function f(x) with (x + 2), like so:

f(x + 2) = 3(x + 2) - 4

f(x + 2) = 3x + 6 - 4

f(x + 2) = 3x + 2
