The graph of f' (not f) is given below. x1 x2 x3 x4 x5 x6 At which of the marked values of x is A. f(x) greatest? x = B. f(x) least? x = C. f'(x) greatest? x = x2 D. f'(x) least? x = x4 E. f" (x) greatest? x = x1 F. f" (x) least? x = x3 用 (Note that this is a graph of f', not a graph of f.)

Use a calculator to evaluate fx=8x at x=2.

How do the graphs of the functions f(x)=x2 and f(x)=x21 differ? We graphed them at the start of this section. What is the difference between their graphs? How are their graphs the same?

In your own words, explain the difference betweena relation and a function.

If f(x) =  1 / (x3 - 8)   what number(s) are not in the domain of f?   1. +2, -2   2. 0, -2   3. 0, +2   4. +2

is the point (3,-5) on the graph of function f(x)=3/2x-8? yes, no, impossible to determine

The graph attached shows the curves y = x^3 and y^3=x. a.) Explain why both of these curves are functions. b.) For the curve y^3=x, write y as a function of x.

A rectangular plot of ground is to be enclosed by a fence and then divided down the middle by another fence. The fence down the middle costs Php 40 per running foot and the other fence costs Php 50, and Php 30000 worth of fencing materials is to be used. Let x feet be the length of the fence down the middle. Express the number of square feet in the area of the plot as a function of x.
