Question 129582
Graphing calculators operate a little differently depending on the make and model. 
.
On my graphing calculator (TI-89) I can just press a key with a green diamond on it and then 
press the F1 key and then enter the function 5x^2 - 3x + 2. Then I press two keys, the green
diamond key and the F3 key to get it to graph. I'm not sure about how to do it on other makes
and models.
.
But if you do get your calculator to graph the function, here's what you should see:
.
{{{graph(600,600,-5,5,-5,30,5x^2-3x+2)}}}
.
Hope this helps you to check your answer.
