Question

Which function is a quadratic function?

p(x) = 2x(x2 + 6) + 1
m(x) = –4(x + 3) – 2
t(x) = –8x2(x2 – 6) + 1
h(x) = 3x(x – 2) – 4

Answer 1

the last one bec when multiply the outside number by what’s in the parentheses u get x^2. the other equations get u x^4, x, x^3. quadratic is only x^2
