[From: ] [author: ] [Date: 11-10-02] [Hit: ]

I have NO CLUE how to do this! D: can someone walk me through it? I need to know it for a test soon!For y = 2g(x) range will be enlarges by a factor 2 i.e.Got a clue at least now?......

The domain of y=g(x) is -5 ( what is the domain and renge for y=g(1/4x)?
and the domain and range for y=2g(x)?
they need to be in form of inequalities. I have NO CLUE how to do this! D: can someone walk me through it? I need to know it for a test soon! :(

For y = g(1/4x) imagine that 1/4x is u so y = g(u) and so -5 ( -5 ( For y = 2g(x) range will be enlarges by a factor 2 i.e. -28 ( Got a clue at least now?
