Then evaluate the function for several values of x, and use the resulting points to graph the function. Show your work; f(x) = -x2 + 2x - 1 Answer by stanbon(60771)   (Show Source): You can put this solution on YOUR website!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. Show your work; f(x) = -x^2 + 2x - 1 -------------------------- a = -1 ; b = 2 ; c = -1 -------------------------- x = [-2 +- sqrt(4 - 4*-1*-1)]/-2 ------------ x = [-2 +- sqrt(0)]/-2 x = 1 with multiplicity two ---------------------------------- ----------------------------------- Cheers, Stan H.
