Logarithms Exam

Match the graph with its equation

• y = log₄ (x)+2

• y = log₄ (x + 2) + 1 

• y = log₄ (x - 1) + 2

• y = log₄ (-x + 2)

Log with a base "e" (log_e) is the same thing as...

• "e"

• Natural Logarithm (LN)

• Common Logarithm (Log)

• Natural Log, base "e"
  LN_e

Write the expression as a single logarithm. Then simplify as much as possible
log₅3 + log₅6 - log₅2

• log₅69

• log₅9

• log₅162

• log₅98

Write the expression as a single logarithm.   Then simplify if possible.
log 6 - log 3 + 2 log 7

• log 98

• log 78

• log 56

• log 45

• -5 does not match the base of the logarithms.

• -5 is less than the output of the equation.

• Plugging in -5 for x results in a negative argument.

• Plugging in -5 for x results in a positive argument.
