Question

I've been working on this function for quite awhile and just can't seem to get it.

Inputs x 5, 6, 7, ?
Outputs y 50, 72, 98, ?

I need the equation too.

Please help!

Answer 1

5 * 10 = 50
6 * 12 = 72
7 * 14 = 98
8 * 16 = 128

Answer 2

or

5 ---> 50 = 2(25) = 2(5^2)
6 ---> 72 = 2(36) = 2(6^2)
7 ---> 98 = 2(49) = 2(7^2)

equation:
y = 2x^2
