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

X-intercepts are the points where the graph crosses the x-axis. Along the x-axis value of y-coordinate is zero. So if we equate the given equation to 0, we can find the points where y-coordinate is zero and thus we can find the x-intercepts of F(x).



Taking square root of both sides we get:



The square root of -5 will result in a complex number. So we reject this value and only consider 

Taking the square root again, we get:


Thus the F(x) has two x-intercepts at  and

The answer simplified would be. -6300x
