A data set contains an independent and a dependent variable. Which must be true of the data set if a linear function can be used to represent the data?

The table represents a function f(x). what is f(3)? a.-9 b.-1 c.1 d.9

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?

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)
