Comparing Exponential Representations

• Function 1 has a greater initial value; the y-intercept is $2.10.

• Function 1 has a greater initial value; the y-intercept is $2.50.

• Function 2 has a greater initial value; the y-intercept is $2.00.

• Function 2 has a greater initial value; the y-intercept is $2.70.

Is the table linear, exponential or neither?

• Linear

• Exponential

• Neither

Is the graph linear, exponential or neither?

• Linear

• Exponential 

• Neither

Compare the following functions: Y(x) is shown in the table and f(x) = 95(1.25)^x Which statements are true? Show work (hint: make a table for f(x) and find the growth factor for y(x)).

• When x>3, f(x) will exceed y(x)

• g(x) will reach 120 first.

• f(x) has a smaller y intercept compared to y(x)

• From 0 <x < 2, g(x) has a faster rate of change.
