Define the sequence W so that W(n) is the number of white squares in Step n, and define the sequence B so that B(n) is the number of black squares in Step n.

1. Write an equation for sequence B.

2. Is the number of black squares ever larger than the number of white squares? Explain how you know.

At which value in the domain does f(x) =0?

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.

Which of the following exponential functions goes through the points (1, 6) and (2, 12)? f(x) = 3(2)x f(x) = 2(3)x f(x) = 3(2)−x f(x) = 2(3)−x
