Question

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? (6 points)

Part B: Which function has a greater y-intercept? (4 points)

Answer 1

g(x) is written in the slope-intercept form. Its slope and y-intercept should be obvious.

For f(x), note that
y changes by 2 when x changes by 1
f(0) = -1
