Answer 1

\(y = kx^2\)

\(48 = k(4)^2\)

Can you solve for \(k\)?

Answer 2

k = 3 @iGreen

Answer 3

Yep, now see what y is when x = 2.

\(y = kx^2\)

\(y = (3)(2)^2\)

Can you simplify that?

Answer 4

y = 12 @iGreen

Answer 5

Right, so when x = 2, y = 12.

And there's only one graph with (2, 12) in it..and which is that?

Answer 6

@iKayla Got it?

Answer 7

Is it C? @iGreen

Answer 8

Yep! You got it!
