an arithmetic sequence has this recursive formula {a1=7 {an=an-1-4 what is the explicit formula for this sequence

The graph shown is the graph of which function?

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

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)
