Write out the log equation for this graph: y= logbase(x)
(0.25, -1)
(1,0)
(4,1)
(16,2)
First we have to calculate the value of base from the given points,
"\\Rightarrow y= log_{b}x\\\\\\Rightarrow b^y=x"
So from given point (0.25,-1)
"\\Rightarrow b^{-1}=0.25\\\\\\Rightarrow b=4"
So, above equation becomes "\\boxed{y=log_4x}"
and Equation of above graph is:
