Question 247798: Use the quadratic formula to determine the x-intercepts (if any) of the following function. Then evaluate the function for several values of x, and use the resulting points to graph the function.
f(x)=-x^2+1

To find the x-intercept, set f(x)=0 and solve for x.
-x%5E2%2B1=0
-x%5E2=-1
x%5E2=1
x=1 and x=-1
When x=0, f(x)=1
When x=1=-1, f(x)=0
When x=2=-2, f(x)=-3
When x=3=-3, f(x)=-8
