The graph of y=5X^2-5 is the graph of y=X^2-1 stretched vertically or horizontally?
I get that it streches by 5 but how do i tell if its vertical or horizontial?
What are the x and y intercepts of F(x)=4xsquared-1?
i got +or-1/8 for the x intercept but im sure its wrong. I thought i got it in class but i guess not. Why is math pure 30 required for college :((Headbang)
