How many x intercepts appear on the graph of this polynomial function?
f(x) = x^4 - 5x^2
a) 1 x intercept
b) 2 x intercepts
c) 3 x intercepts
d) 4 x intercepts

Option C -3 x-intercept

Step-by-step explanation:

Given : Polynomial function

To find : How many x intercepts appear on the graph of this polynomial function?

Solution :

To find the x-intercept we put y equals to zero.

Let

Now, Substitute y=0

We solve for x,

So,

Which means there are three x-intercept.

Therefore, Option C is correct.
