1
If the point (3,8) is on the graph of y = 2^x, then this point is on the graph of y = log₂x
(8,3)
(3,8)
(1,2)
(0,1)
2
Rewrite the equation log₄64 = 3 using logarithms
log464 = 3 since 34 = 64
log464 = 3 since 464 = 3
log464 = 3 since 43 = 64
log464 = 3 since 644 = 3

Why do we learn about logarithms?
They are the inverses of exponentials
They have no purpose & never used in upper levels of math
They help us with rewriting exponential equations
The alignment to the common core is the only reason
4

Score on the richter scale
The half life of a radioactive substance
Amount of money in a bank that compounds the interest earned
Atmospheric pressure

By the definition of Common Logarithm...
log x = y is the same as ey = x
log x = y is the same as ex = y
log x = y is the same as 10y = x
log x = y is the same as 10x = y
9
If a logarithm is the inverse of exponential growth, then the logarithm graph will have
a vertical asymptote
no asymptotes
a horizontal asymptote
an oblique asymptote
