Question 1132698
Have you tried picking x and evaluating the corresponding y?


Have you learned how the shape of parabola from equation works?



{{{y=x^2}}}
Get familiar with this shape and placement on coordinate rectangular system.


{{{y=-2x^2}}}
The negative 2 makes vertex as a maximum point and stretches the graph vertically.


Can you figure which equation goes with which graph?


{{{graph(300,300,-10,10,-10,10,x^2)}}}


{{{graph(300,300,-10,10,-10,10,-2x^2)}}}


{{{graph(300,300,-10,10,-10,10,(1/4)x^2)}}}
