Complete the following diagram sagittals and connect each pre-image with its respective image.
a) X f(x) = 2x y
b) X f(x) = 5x - 2 y
c) X f(x) = x + 3 y
I. The function f(x) = 2x is represented in diagram a.
II. The function f(x) = 5x - 2 is represented in diagram b.
III. The function f(x) = x + 3 is represented in diagram c.
IV. To determine the values that correspond to each pre-image in a sagittal diagram, we evaluate or replace them in the function.
