I don't understand how to do this problem? Someone help me, please

OpenStudy (igreen):

Use the rule \(\sf (x, y) \rightarrow (-x, y)\)

OpenStudy (igreen):

Multiply -1 to all the x-values..those are your new set of points.

Oops! Sorry! That was my mistake. Here

OpenStudy (igreen):

Okay, can you multiply -1 to all the x-values of those three poitns?

OpenStudy (igreen):

points*

OpenStudy (anonymous):

\[-1 \times 0=0\] for D \[-1 \times -3=3\] for E \[-1 \times 3=-3\] for F, rite? Is this what u were asking for?

OpenStudy (igreen):

Correct..so replace those x-values with the x-values of the original points. \(\sf (0, 3), (-3, -1), (3, -2)\) Becomes: \(\sf (0, 3), (3, -1), (-3, -2)\) That's our answer.
