Question

A linear function, f(x) passes through the points (2,8) and (5,17). The function was

replaced with f(x + k) resulting in the function g(x). The function g(x) passes
through the points (2,14) and (5,23). What is the value of k?

Answer 1

k = 6

Explanation:

(2,8) and (5, 17) each moved up 6 units from f(x) which is why k = 6
