Rowan wants to justify that f(x) 3x-7 is a linear function. if she evaluates f(x) for consecutive integer values, which statement justices the claim that f is a linear function?
a. there is a common difference of -7 for f(x) when x increase by 1
b. there is a common factor of -7 for f(x) when x increase by 1
c. there is a common different of 3 for f(x) when x increase by 1
d. there is a common factor of 3 for f(x) when x increase by 1

What is the greatest common factor of 6a, 8a^{2}, and 14?

The rectangle on the right is the image of the rectangle on the left. what transformation would result in this image? reflection rotation translation dilation

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
