Question 29128
There are different ways to graph this. It is already in slope-intercept form, so we will graph that way;
slope-intercept form= y={{{mx^2}}}+b, 
m= slope
b=y-intercept
Your y-intercept= -3, so from the point (0,-3), move up 1 unit and to the right 4. Then from that point again, up 1 unit and to the right 4.
