When you multiply a function by -1 what is the effect on its graph a. graph flips over the line y=x b. graph flips over the line y-axis c. graph flips over the x-axis

The values of the function (the ' y' values) change sign so the graph flips over the x-axis.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
