Logarithms By: Allie, Jess, Emily, and Katie
Logarithms This is usually written as This reads, y equals log base b of x.
Textbook Definition Logarithmic Function- The function , where b>0, and b≠1, which is the inverse of the exponential function .
Algebraic Definition logbx=y if and only if by=x
In Our Own Words… If , we can also say that . When we say that , it means that y is the number we have to raise b to, in order to get x.
Logarithmic and Exponential Form • Logarithms Are the inverse of Exponential Functions • So… if then Log8=3 • This is important, because Logarithms are solved and graphed in exponential form.
Example =(2*2*2=8) Y=3
Solving Logarithms y=3 b=12 x=81
