Question 155231
f(x) = 4x² + 3x - 7 
-----------------------
1st: You can find examples of graphing using Google.
-----------------------
2nd: You will need to plot at least three points to develop
a graph for your problem.
Let x = 0, then f(0) = 4*0+3*-7 = -7 giving you point (0,-7)
Let x = 2, then f(2) = 4*2^2 + 3*2 -7 = 16+9-7 = 15 ; point (2,15)
Let x = -2, then f(-2) = 4(-2)^2 + 3*-2 -7 = 16-6-7 =3: point (-2,3)
------------------------------
Plot these points and more, if you wish, then connect the points with
a smooth curve.
You should get something like the following:
{{{graph(400,300,-10,10,-10,10,4x^2+3x-7)}}}
