y:    ?    ?   ?  ?  ?

anonymous · Answer

Just put the x-values in the function, I'll do the first: x=-4, y=7(-4)^2+7=119

anonymous · Answer

y = 119,35,7,35,119

anonymous · Answer

thats too much

anonymous · Answer

What do u mean?

anonymous · Answer

im suppose to graph this and compare it to y=x²

anonymous · Answer

Well, that shouldn't be a problem.

U get another table (use same x values or any values u like) and plot them on same graph.

anonymous · Answer

but for the y=7x²+7 do i write x: 7  1  0  1  7 or am i wrong?

anonymous · Answer

So far u have

x: -4 -2 0 2 4
y: 119,35,7,35,119 from mathematicalpro for 7x^2 +7

Plot those.

On the same graph plot

x: -4 -2 0 2 4
y:                            for x^2 ( u can fill in the y values).
