Question

Hi I have a question I havent done this in a long time and I have forgot how to do it

How do you graph a function? For exampl< how do I graph f(x) = –x3 + 2 by hand

Answer 1

hey @Shadowthieve , it's pretty simple :)
you know that the +2 is the y intercept for this function, so you can place your first point there. Because the x is negative, you know it will start it the upper left quadrant and end in the lower right quadrant. the three represents the slope of the line. so for ever 1 unit in x you move to the left or right, you will move either 3 up (if you move x to left) or 3 down (to the right).

Answer 2

Thanks seems simple enough :)
