Comparing Functions and Initial Value

• The function f(x) has a greater y intercept than the function g(x)
• The function g(x) has a greater rate of change than the function f(x)
• The function g(x) has a greater y intercept than the function f(x)
• The rate of change for both g(x) and f(x) are equal 

• The y-intercept of the function f(x) is less than the y-intercept of the function g(x) 
• The y-intercept of the function f(x) is greater than the y-intercept of the function g(x)
• The y-intercept of the function f(x) is equal to the y-intercept of the function g(x)
• The y-intercepts cannot be determined

Compare the initial values of the functions.

• Both functions have the same initial value.

• The initial value of item I is greater than the initial value of item II.

Compare the initial values of each function.

• The initial value of item I is greater than the initial value of item II.

• The initial value of item I is equal to the initial value of item II.

• The initial value of item II is greater than the initial value of item I.
