i need serious help, I'm trying to plot table of values for sketching graph (parabola)for y=x^2-5x+3

Question

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.

Answer 1

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)

Answer 2

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