This is the formula for exponential functions.
What is y=a(b)x?
Does the table display exponential or a linear model?
Linear; The y-values decrease (subtract) by 1 each time!
Linear or exponential: It costs 40 dollars to join a gym and an additional $10 per month.
Linear
The Common Difference/Common Ratio of the Sequence 2, 4, 8, 16, 32...
What is 2?
Write the linear equation that passed through the two points:
(0,7) and (3,16)
y = 3x + 7
This is the formula for linear
y= mx+b
Does the table display exponential or a linear model?
Exponential; the y-values double (multiply by 2) each time!
This is the model that best describes the following information. y = 17(2)x
What is exponential?
The Common Difference/Common Ratio of -20, -23, -26, -29...
What is -3?
Write the exponential fuctions that passes throught the two points:
(0,2) and (1,6)
y = 2(3)x
If f(x) = 5x+2, find f(7).
32
Does the table display exponential or a linear model?
Exponential; the y-values are multiplying by 6 each time!
This is the model that best describes the following information. {(1,8), (2,12), (3,16), (4,20), (5,24)}
What is linear?

What is 1?
(0, 180) , (1, 160), (2, 140), (3,120)
y = -20x +180
This is the answer when f(x) = 10(5)x is evaluated for f(3).
