Question

Select all of the following functions that are quadratic.

y = 2x2

3 = 2x2 – 8

y = –2 + 2x – 8

y + 3x = 2x2 – 8

y +3x2 = 2x + 3x2 – 8

Answer 1

it is important to note that quadratic functions have the highest power of 2

\(y=ax^2+bx+c\)

Before you select you have to make sure they are in that form (Simplify second, fourth and fifth choices)

Answer 2

Ok. Thx
