Question

@iGreen.

Answer 1

will take a min. multiple graph answers

Answer 2

Variable y varies directly with x^2, and y = 48 when x = 4.

Which graph represents the quadratic variation?

Answer 3

We can graph it.

Answer 4

Plug in the numbers into the equation:

\(y = kx^2\)

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

Simplify and solve

Answer 5

4^2 = 16

Answer 6

48/16 = 3

Answer 7

but i have no idea how to graph it lol

Answer 8

Yes, so the constant is 3..so our equation is:

\(y = 3x^2\)

Here's the graph:
