Question

Which function is a quadratic function?

h(t) = 12 – 8t + 6t3
g(t) = 7t2 + 3t3 + 2t
k(t) = 3t4 + 3t2 + 4
h(t) = 12 – t + 6t2

Answer 1

h(t) = 12 – t + 6t^2

Explanation:

The quadratic function

Answer 2

Answer: Choice D

Reason:

The largest exponent is 2, which makes choice D a quadratic.

Choices A and B are cubic equations because their largest exponent is 3.

Choice C is a quartic because the largest exponent is 4. Quartic has a similar spelling to quadratic, but they are different things. A quartic is a fourth degree polynomial.
