Decide whether h(x)=−x3+2x2−15x7 is a polynomial function.

Question

Decide whether h(x)=−x^3+2x^2−15x^7 is a polynomial function.

If the function is a polynomial function, write it in standard form.

Answer 1

If you rewrite it in the order

h(x) = -15x⁷ - x³ + 2x²,

you will see it is a polynomial written in standard form.
