Question

The table below represents a linear function f(x) and the equation represents a function g(x):

x f(x)
−1 −7
0 −1
1 5
g(x)

g(x) = 5x − 4


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)

Answer 1

f(x) = 6x -1. You can use the formula for slope and point slope form to find this.

1. The slope of f(x) is steeper than that of g(x)

2. The y intercept of f(x) is greater than that of g(x) because -1>-4
