Find the value of the coefficient of 1/x in the expansion (2x-1/x)^5

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −5 0 −1 1 3 g(x) g(x) = 2x − 7 part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) part b: which function has a greater y-intercept? justify your answer. (4 points)

Just tell me how to set up the equation.

A. what does the point (4, 122) represent? b. what is the unit rate? c. what is the cost of buying 10 tickets?
