How do you graph an equation with an absolute value on the Casio fx-9750G graphing calculator?

Question

an example would be: y=x(2x+5) but the parenthesis would be the absolute value

Answer 1

Hi,
I haven't used an fx-9750G, but I have an fx-9850GB which some students have told me is the same thing except for the colors. So, here's how to do it with the fx-9850GB:
a) Of course, highlight the GRAPH icon and press EXE to go to the Y= screen.
b) Press the button for x (x, 0, T); then press OPTN, F5 for NUM, and F1 for abs.
c) Enter your equations so that the entry looks like this: Xabs (2x+5).
d) Press EXE; then F6 to "DRAW" the graph.

Hope this helps.
