Question

based on the function F(x)=x^4-3x^2-1 and the graph of G(x) below, which of the following statements is true?

Answer 1

Answer:

Step-by-step explanation:

A function has a root only if cuts the x axis .

If it cuts once it means it has one real root, if twice then two roots and so on .

Here in the graph of G(x) shown ,it never crosses the x axis so we can say that there is no real root of the given function G(x).

It means the option A which states G(x) has zero roots is correct.
