Question

The points (0, 0), (1, 4), (2, 16), and (3, 36) are on the graph of a function.

Write an explicit function that can be used to represent the function.

Answer 1

y=4x^2

It's an upward opening parabola with vertex at the origin

y=a(x^2) plug in any other point and solve for a

4=a(1^2) = a
