A theater can seat 918 people. The number of rows is 7 less than the number of seats in each row. How many rows of seats are there?

Use the function nest to evaluate p(x) = 1 + x + · · · + x50 at x = 1.00001. (use the matlab ones command to save typing.) find the error of the computation by comparing with the equivalent expression q(x) = (x51 − 1)/(x − 1).

40 describe the outliers from the scatter plot.

Which graph represents the function g(x) = |x + 4| + 2?
