Question

The function f(x) goes through the point (1, 8). What point will this translate to in the function f(x) = (x - 4) + 5?

Answer 1

A. (5, 13)

Explanation:

The function f(x) = (x - 4) + 5 is the translation of the function f(x) 4 units right and 5 units up and the rule is:

(x, y) → (x + 4, y + 5)

Apply the rule to the given point to get:

(1, 8) → (1 + 4, 8 + 5) = ( 5, 13)

Correct choice is A
