Use Descartes' Rule of Signs and the Rational Zeros Theorem to find all real zeros, then use the zeros to factor over the real numbers.

f(x) = x^4 + 6x^3 + 11x^2 + 12x + 18

PLEASE HELP ME!!!!!

1. Suppose that 'a' and 'b' are positive constants.. Consider the function: f(x)=e^[-(x-a)^2/2b]
a.) determine the absolute max of this function and the corresponding x-value.
b.) determine the max and min. rates of change of this function and hte corresponding x-values.
c.) give a verbal description of the graph of htis function that includes the significant features.


This has something to do with L'Hopitals Rule, derivatives, increasing and decreasing tests, and inflection points.
But how do I do any of that without any numbers?!?!?!

A suspension bridge with weight uniformly distributed along its length has twin towers that extend 75 meters above the road surface and are 400 meters apart. The cables are parabolic in shape and are suspended from the tops of the towers. The cables touch the road surface at the center of the bridge. Find the height of the cables at a point 100 meters form the center. (Assume that the road is level)

Can you please explain how you found your answer?

I have no clue where to start here.

if we know that (3.5,-30.25) is the vertex of the parabola below, figure out 3 more points that would also be on the parabola. Explain how you know that your 3 points are on this parabola even though we don't know it's quadratic equation.

Other points already given on parabola besides the (3.5,-30.25) are (4,-30) (6,-24) (10,12)

I'm stressing out trying to solve this.
