Do I make a table of y values and plug them in for x? I keep getting the wrong answers on my online homework :( I have a test tomorrow. Please help! Thank you! Answer by solver91311(24713) (Show Source):
You could make a table of values and then calculate the -values that correspond. But it would probably be helpful to compare this equation to the equation of a parabola with vertex at , namely
That gives you the vertex directly and allows you to plot two points for every one you calculate after that because of symmetry.
