Question 1

Plug in the points x= -2, -1, 0, 1, 2 into the quadratic $y=x^2$. Write your answers as y=a,b,c,d,e (no space) with the values for y in the same order as the x values. For example if I plug -2 into the quadratic I will get and answer for a. If I plug 1 into my quadratic I will get the answer for d. Use graph 1 to write down the equation, the x and y values, plot the points and then draw a parabola connecting the points. You will use this to compare answers later.
