• no solution
• only 6
• 6 and -2
• 3

log₄(3x-1)=log₄(2x+3)

• 4

• 3

• 1

• 8

log(2x) - log(5) = log(30)

• 6/5
• 45/2
• 75
• -3/8

log ₇ 10 + log ₇ (2x + 5) = 2

• x = 17

• x = -1/20

• x = -9/5

• x = -13/2

Solve for x:

log₂(2) + log₂(8x) = 6

• x = 3

• x = 2

• x = 6

• x = 4

What is the equation of the asymptote?

• x = -3
• x=5
• y= -3
• y=5

Logarithmic functions are the inverse of...

• Linear Functions
• Exponential Functions 
• Quadratic Functions 
• Polynomial Functions 

Match the graph with its equation

• y = log₆(-x) + 1
• y = log₆(x − 2) + 1
• y = log₆(x + 2) - 1
• y = log(x-8) + 1

Write the expression as a single logarithm.   Then simplify if possible.
log₅3 + log₅6 + log₅9

• log₅69
• log₅56
• log₅162
• log₅98
