Exponential and Log Functions

Find the inverse of y=9^x

• y=log_x9

• y=log₁₀9

• x=log_y9

• y=log₉x

When raising one power to another we do what to the exponents?

• multiply the exponents

• subtract the exponents

• add the exponents

• divide the exponents

Evaluate the following logarithm:

log₃27

• 3

• 2

• -3

• ¹/₃

Re-Write the Logarithm Equation into Exponential Form
log_hw = d

• w = h^d

• w^d = h

• h = w^d

• h^w = d

Rewrite log_vn = a in exponential form.

• v^a = n

• n^a = v

• vⁿ = a

• aⁿ = v

In an exponential function, what does the 'a' represent? 

• SLOPE

• RATE OF CHANGE

• Y-INTERCEPT

• COMMON RATIO

• 1

• 2

• 3

• 4

Which of the equations could best describe the graph?

Match the following log functions to their horizontal shift (which way will the asymptote shift)

• Shift Left

• Shift Right

• No Horizontal Shift

• left 3, right 1

• right 3, down 1

• right 3, up 1

• left 3, down 1
