1) Graph the quadratic function y = -4x^2 + 4x - 8 on an x-y coordinate, plane by hand. Label each point that you use to draw the curve. DO NOT simply sketch the graph you see after plugging the equation into a calculator.
[hint: first build an x-y table, using x = -3,-2,-1,0,1,2,3,]
2) Use the graph of the equation above to estimate where the function's x-intercepts are. (recall that this is where the function crosses the x axis)
3) Explain in your own words why the graph of a quadratic function containing an "x^2" term (like the one above) can never be a straight line.
