Which of the following exponential functions represents an initial value of 1780 and a growth of 18% for x years?​

(a)  

Classify the model as Exponential GROWTH or DECAY. A=1200(.85)^-6x

• Growth

• Decay

Select all the equations that represent exponential decay.

Write in logarithmic form.
2^-4 = ¹/₁₆

• log₂(¹/₁₆) = -4
• log_-4(¹/₁₆) = 2
• log _-4 2 = ¹/₁₆
• log₂(-4) = ¹/₁₆

Convert log₈(x+2)=3 to exponential form.

• 8^(x+2)=3
• 3^(x+2)=8
• 8³=x+2
• 3⁸=x+2

Evaluate the following logarithm:

log₄16

• 1

• -2

• 2

• ¹/₂

log₅(4x-7)=log₅(x+5)

• 3
• 12
• 4
• 7

Convert 6^(x+2)=216 to logarithmic form

• log₂₁₆(x+2)=6
• log₆(x+2)=216
• log₆(216)=x+2
• log_(x+2)(216)=6

Solve

• 8

• -8

• 1/8

• -1/8
