Question

When you multiply a function by -1, what is the effect on its graph?

A. The graph flips over the x-axis.
B. The graph flips over the line y = x.
C. The graph flips over the y-axis.

Answer 1

Why don't you plot the function \[y = x^2\]from \(x=-2\) to \(x=2\)

Next, plot the function \[y = -1*x^2\]over the same range. Discuss.
