How do you graph this with a scientific calculator and not a graphing calculator?

With graph-paper & pencil (& the calculator)!

Can you graph the function:

y = 3x² + 5x - 8

or

y = cos(x)

or

y = sin²(x)

using the scientific calculator?

I can graph these equations

y = 3x² + 5x - 8

or

y = cos(x)

or

y = sin²(x)

but what I am suppose to graph in the images?
