Solve this equation for y.

Use the log rules:2.a. Given that y=3logb 4-2logb 8-logb 3 express y as a single logarithm to base b. Find the value of y when b=3

If b = 3 then y = -1

to a) Determine domain and range of f. Then you know the domain and range of too. Swap x for y to get the equation of ....

3. Consider these two functions: f(x)= 3/x-4 x cannot be equaled to 4 and g(x)=x2 (squared)

a) find the inverse function f-1(x) and clearly state any values of x for which the inverse is not defined

b) find the composite functions f o g (x) and g o f (x) , clearly stating any values of x for which these composites are not defined.

Only for the records:

to b)
