Make a table of values and graph the quadratic function y=3/4x^2

Question

 

---

x	y=3/4x^2	(x,y)

 

Answer 1

x	y=(3/4)x^2	(x,y)
-1	0.75	(-1,0.75)
0	0	(0,0)
1	0.75	(1,0.75)

For a quadratic (parabola) it's important to include the vertex, which is (0,0) here.

It's important to show that negative x gives the same value for y as the corresponding positive value of x. Adding points (-2,3) (2,3) would help to show the spread of the parabolic arms. This demonstrates the symmetry as well as the shape.
