- How many x-intercepts appear on the graph of this polynomial function?
You can find the number of x intercepts by setting f (x) equal to zero giving you 0=x^4-5x^2 You can factor out an x^2 and divide on both sides (when you divide 0 by anything it is still zero so the x^2 disappears), and you are left with 0=x^2-5, which you can solve easily giving you x=+ - sqrt (5)
