You can put this solution on YOUR website!
y=x^2+2x-3
the easiest way is to use a table of values. you can pick a few numbers for x, plug them in and solve for y.
.
for example, if x = 1, y=1^2 + 2(1)- 3 = 0, so one point is (1, 0)
pick othe values for x such as 0, -1, -3, -4, 1, 3, 5.
.
plug each number in (one at a time) and solve for y. this will give you a lot of points. plot the points on a graph and connect the dots. the graph should look like this:
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+x%5E2%2B2x-3%29+
