Webwork give the x-coordinate of a point where:

a. the derivative of the function is negative: x=

b. the value of the function is negative: x=

c. the derivative of the function is smallest (most negative): x=

d. the derivative of the function is zero: x=

e. the derivative of the function is approximately the same as the derivative at x=2.75 (be sure that you give a point that is distinct from x=2.75! ): x=

If f(x)= 3x+6 which of the following is the inverse of f(x)

A.s.a.! this is a similarity in right triangles. next (solve for x)a.) 12b.) 5c.) 12.5d.) [tex] 6\sqrt{3} [/tex]

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
