What type of function is f(x)=2(1/7)^x ?

• Exponential Growth

• Linear

• Exponential Decay

• None of the Abovee

Convert 16 = 2^x to a Log

• Log₂(x) = 16

• Log₂(16) = x

• Log₁₆(x) = 2

• Log_x(16) = 2

Expand the expression: log₂5xy

• log₂5 + log₂xy

• log₂5 + log₂x + log₂y

• log10xy

• xylog₂5

Expand the expression: log₂10x

• log₂10 + log₂x

• log10 + logx + log2

• log₂10x

• xlog₂10

Condense the expression: log₄6 + log₄3

• log₄2

• log72

• log₄63

• log₄18

Condense: log₆x - log₆y

• log₆y - log₆x

• log₆x + log₆y

• log₆x/y

• log₆y/x

Solve for x: log₃(x+4) = log₃(5x)

• x=5

• x=4

• x=1

• x=3

log (2 / 3) = ?

• log 2 + log 3

• log 2 / log 3

• log 2 - log 3

• 2/3 * log 1

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

• Growth

• Decay

Solve for x:
e^x=7

• x=ln7

• x=ln⁷

• x=7^ln

• No solution
