i need serious help, I'm trying to plot table of values for sketching graph (parabola)for y=x^2-5x+3
xy values are 0,3 1,-1 2.5,-3.25 3,-3 4,-1 5,3 6,9

are these values correct, I'm having problems graphing.

    Let me help you. Choose easy x

    x= 0, 1, -1, 2, -2, 3, -3
    then y will be
    y=3, -1, 9, 9, 17, -3, 27

    and your 2.5 looks like a good point to do for a sketch, (5/2, -3.25)

    So am im posting the graph with 2.5 and -3.25?

    Is this correct? Evaluate the exponential equation for three positive values of x, three negative values of x, and at x=0. Show your work. Use the resulting ordered pairs to plot the graph; y=(1/4)^x+3 x = -1, y = 7 x = -0.5, y = 5
