HELP 1.) For what values of b is the function f(x)= b^x increasing and for what values of b is the function decreasing?

2.) What transformation occurs on the function f(z) b^x increases from 1

3.) How are the functions g(x) = b^x and f(x) = (1/b)^x related? waht trasnformation maps one onto the other

4) what is the relationship between the function f(x)=b^x and g(x) = logb(x)

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?
