On a piano, the formula to determine the frequency f of any pitch relative to the a above middle c (a440) is given by the expression f(x)=440(2)x/12, where x represents the the number of half-steps above or below a440. which of the following is equivalent to f(x)?

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)
