You can put this solution on YOUR website!
y=x^2+2x-3
\n" ); document.write( "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.
\n" ); document.write( ".
\n" ); document.write( "for example, if x = 1, y=1^2 + 2(1)- 3 = 0, so one point is (1, 0)
\n" ); document.write( "pick othe values for x such as 0, -1, -3, -4, 1, 3, 5.
\n" ); document.write( ".
\n" ); document.write( "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:\r
