You can put this solution on YOUR website! Find the domain and range of the function and the inverse ?
a, base3logx^2-4
----
Question:: Do you mean y = log3[x^2-4]
If so,
Domain:: ?
Solve x^2-4 > 0
x^2 > 4
Domain:: All Real Numbers where x < -2 or x > 2.
-----
Range: All Real Numbers
-----
Inverse::
1st:: Interchange x and y to get
x = log3(y^2-4)
2nd:: Solve for "y"::
y^2-4 = 3^x
y^2 = 3^x+4
y = +/-sqrt(3^x + 4)
