The linear function in the graph shows the value, in dollars, of an investment in years after 2012.

The exponential function in the table represents the balance of a savings account, in dollars, over time in years after 2012.

Years since 2012 Savings account balance ($)
2 180
3 540
4 1620
5 4860

Drag the correct answer to the box to complete the statement.


The y-intercept of the exponential function is______ the y-intercept of the linear function.

A) approximately 130 more than

B) approximately 130 less than

C) approximately 30 more than

D) approximately 30 less than

Respuesta :

exponential fn:

2 180

3 540

4 1620

5 4860

each year is 3x of year be4

so year 0 (2012) is 180/3/3 = 20

y-intercept of linear fn (2012) is 150

The y-intercept of the exponential function is approximately 130 less than the y-intercept of the linear function

ans is B

The linear function in the graph shows the value, in dollars, of an investment in years after 2012; with the y-intercept between 140 and 160.


The exponential function in the table represents the balance of a savings account, in dollars, over time in years after 2012:

Years since 2012 Savings account balance ($)

2 180

3 540

4 1620

5 4860

Each year the balance increases by a factor of 3. So the y-intercept at Year 0 = Year 2/3^2 = 180/9

=20

That is approximately 130 less than the y-intercept of the linear function.


The answer is B.
