Graphing a polynomial function that is a quadratic; so for this particular problem we are just looking at the base quadratic function y equals x². Okay we have a chart with some numbers we are going to fill up the chart and then plot the points to see what this graph looks like.
If x is 2, we plug in 2, –2² we have 2 2 so 2 times 2 negatives cancel leaving us with 4. We plug in 1, 1² again the negatives cancel leaving us with 1, 0² is 0, 1² 1 and 2² is 4. Now we have a table and we can go and plot these corresponding points. Not going to make my graph exact because I'm not concerned with the exact position I just want to sort of get a rough idea of what this looks like.
Okay, plot in points x is 2 y is 4 over 2 we go up to 4, (1,1), (0,0), (1,1) and (2,4) connecting our dots we end up with a basic parabola. So y is equals f(x) is equals x² quadratic function will give us base graph of a parabola or just a 'U' basically looking graph.
