Choose the equation for the red graph
Leona [35]

The red line is a reflection across the x-axis, so the correct option is d.

<h3>How to write the equation for the red line?</h3>

First, we know that the black line is represented by y = f(x). Here, we can see that the red line is given by a reflection around the x-axis.

This reflection only changes the sign of the right side, then we get that the function of the red line is:

g(x) = -f(x)

Then we can write this as:

y = g(x) = -f(x) = -1*f(x)

If we divide both sides by -1, we get:

y/(-1) = f(x)

Like in option d, so that is the correct one.
