You can put this solution on YOUR website!
(1) f%28x%29=3%5Ex+-+2
(2) f%28x%29=log%282x%29
+graph%28+600%2C+600%2C+-4%2C+4%2C+-4%2C+4%2C+3%5Ex+-+2%2Clog%2810%2C2x%29%29+
The graph shows that {{2x}}} for log%282x%29 can not
be negative. That's because there's no way 10%5Ey
(y = f(x))can possibly be negative.
