Question

Sketch the graph of f(x)=x^3+2x^2-4x-8 by hand.  Make note of the end behavior and all intercepts.  I am studying for a test, plz help

amistre64 · Answer

we really can sketch this for you can we?   Find some points by using values for x to find the values for y and plot the points on a graph and connect the dots....

End behavior for polynomial$$ax ^{n}, (n \ge1)$$

anonymous · Answer

In this case n is odd, the ends will point in different directions. (x^3 is a common function you should know how it looks.)
a>0 down on left, up on the right.
