Question

Which polynomial function does NOT have 0 as a root?
h(x) = x^4 + 3x^2 – x
f(x) = x^4 – 1
k(x) = x^2 – x^3
g(x) = x^2 – 3x

Answer 1

plug in any x that doesn't produce a zero.

Answer 2

I don't understand what you mean

Answer 3

can't be x^4-1

Answer 4

sorry I'm exhausted from last night... x.x

Answer 5

Put x = 0 in each answer and see if the function becomes zero. If it does then zero is a root. If it does not then zero is not a root.
