Question

How do I graph `f(x) = x^5 - 3x^4 + 11x - 9` on a TI-84?

Answer 1

First click on gray button "y="... and choose `y_1=`

then enter the equation using numerical buttons and the button to the right of the "alpha" key. `X, T, theta, n`...

Next you may want to change your "window" also in gray. I've used xmin=-5, x-max= 10, ymin= -5, ymax = 10.
