Question

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

x f(x)
−1 −6
0 −3
1 0
g(x)

g(x) = 4x − 5


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

-3–0=-3 (yum yum over
0–1=-1 the picnic table)

-3/-1= 3

F(x)=3x slope=3
G(x)=4x-5


F(x) has a greater y-intercept because for negatives the smaller the number you see is, the bigger it is in reality.

(0,-3)
-5

3, 5 3 is smaller
-3, -5 in reality 3 is bigger
