Question

Which statement best describes the effect of replacing the function f(x) = 2x − 2 with the function g(x) = 2x + 5? The graph shifts 7 units left. The graph shifts 5 units left. The graph shifts 2 units up. The graph shifts 3 units up. (pls help and explain how you got your answer as well if you could)

Answer 1

Original given function is f(x) = 2x − 2 and transformed function g(x) = 2x + 5.

Please see..

If we add 7 in f function, we get

f(x) = 2x − 2 +7 = 2x + 5 and that is the g function.

According to rules of transformation f(x)+c shift c units up and f(x)-c shift c units down.

We added 7 to f function.

Therefore, it is being shifted 7 units up.
