Which equation describes the relationship of the
graphs of f(x) and g(x)?
g(x) = f(x) + 1
g(x) = f(x) - 1
g(x) = f(x + 1)
g(x) = f(x - 1)

Which of the following is a proper fraction? a. 9⁄8 b. 5⁄6 c. 7⁄3 d. 4⁄2

Which exponential function has an initial value of 2? f(x) = 2(3x) f(x) = 3(2x)

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?
