If you horizontally stretch the quadratic parent function, f(x) = x2, by a factor of 5, what is the equation of the new function? a. g(x) = (5x)2 b. g(x) = x2 c. g(x) = 5x2 d. g(x) = (x)2

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)

What does the sign of the slope tell you about a line?
