Question

Graph the function f(x) = –x3 + 3 by hand (not to be submitted).

Part 1 [3 points] Use complete sentences to explain the process of graphing f(x) = –x3 + 3.
Part 2 [3 points] What is the end behavior of f(x) = –x3 + 3?

Help me please!!!

Answer 1

Is this a calculus or algebra course?

Answer 2

Answer 4

Sorry.

Answer 5

agh, well thanks for helping me with part 2. anyone else out there good at graphing?

Answer 6

So to graph something you look at the term with the highest power, which in this case is -x^3. Think of it this way, the further away you go, the less the +3 is going to matter.

So what if you plug in a really large positive term, what does it look like? Well, -x^3 will approach negative infinity for large positive numbers. Now what if you plug in a really large negative term? It'll just approach positive infinity!
