True/False: The following list of numbers is a geometric sequence.
4,8,12,16,20,24,28...
NO Arithmetic! (Adding = Arithmetic)
Is this exponential function a growth or decay function?
y= -24(1.06)x
Decay, the negative makes the graph go down.
(16x^8)/(2x^2
8x^6
30 + 9
10
Is this function growing or decaying?
y=14(0.5)x
Decaying because the b value is less than 1.
Fill in the next two terms in the following sequence.
-2, 1, -0.5, ______ , ______
0.25 and 0.125
Calla decides to open a nail studio. She starts with $2,200. Unfortunately, London's nail shop is putting Calla out of business! Calla's nail business has gone down 82%. How much money will Calla have after 2 years? Round to the nearest cents.
Hint: y = a(1-r)t
y = 2200(1-0.82)2
y = $71.28

Is the following function linear or exponential?
x -1 0 1 2 3 4
y -13 -10 -7 -4 -1 2
Linear (you add 3 for the y's)

Write the exponential function given (0,12) and (1, 36). Hint: y = a(b)x
y = 12(3)x
4*3^2x^-5
36 / x5
2x^0*3w^-1*5w^0
30/w
Write an exponential function using the form y=a(b)x that goes through the points (0,12) and (2,48).
y = 12(b)x
48 = 12(b)2
4 = b2
b=2
y = 12(2)x
