Question

how could i make a table from y=7x²+7

x: -4 -2 0 2 4
y: ? ? ? ? ?

Answer 1

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

Answer 2

y = 119,35,7,35,119

Answer 3

thats too much

Answer 4

What do u mean?

Answer 5

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

Answer 6

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.

Answer 7

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

Answer 8

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).
