Question

The function y=-5x+2 is transformed by reflecting it over the y axis. What is the equation of the new function?

Answer 1

y = mx + b

When a function is reflected over the y-axis, the b (2) stays the same but the slope (m) changes to its opposite sign.

since the slope is negative in this equation, it will become positive.

so the new fuction will be

y = 5x + 2
