Comparing Y Intercepts of Exponential Functions

The linear function f(x) and the exponential function g(x) are graphed. 
The y-intercept for f(x) is ________ the y-intercept for g(x). 

• greater than

• less than

• equal to

• I do not know

The table represents f(x) while the graph represents g(x). 
The y-intercept of f(x) is _________ the y-intercept of g(x). 

• greater than

• equal to 

• less than 

• I do not know

Jason compared the function f(x) = 20(1.2)^x to the function that fits the values in the table.

What is the distance between the y-intercepts of the two functions?

• 14

• 8

• 6

• 4

Sam graphed the equation y = 2^x + 3 . Did he graph it correctly, why or why not? 

• No, any exponential graph should always intercept the y-axis at -3

• Yes, his graph can have a y-intercept anywhere

• No, his graph was supposed to have a y-intercept at 4

• Yes, his graph was supposed to have a y-intercept of -3

To find the Y-intercept of a Exponential Function, we set X= 0 and solve.

• TRUE

• FALSE

Answer explanation

Given y=3^x determine the y-intercept 

• (0,1)

• (0,3)

• No Y-intercept

• y=1

To find the Y-intercept of a Exponential Function, we set X= 0 and solve.

• TRUE

• FALSE

Answer explanation

• The y-intercept for f(x) is greater.

• The y-intercept for g(x) is greater.

• The y-intercepts are equal.

• Both y-intercepts are negative.
