Find the inverse.





f(x)=5+(logx/log2) Im not sure if the parentheses are needed.





f(a)=a^2 + 4a + 4How can this be done? Please show works so that i can understand.?
switch x and f(x) to find the inverse.





x=5+logf(x)/log2


xlog2-5=logf(x)


all raised to the tenth power is





f(x)=2^x/ 10^5











Switch a and f(a)


a=f(a)^2+4f(a)+4


a=(f(a)+2)^2


f(a)=(a^.5)-2
