Best ResponseYou've already chosen the best response.0\(g(x) = 2x  3\) \(g(2) = 2\cdot 2  3\) Do you see the pattern?

Best ResponseYou've already chosen the best response.0@ onemathcat, you have to be careful with the way you explain things. Let's assume the user understands everything you explain to her , but then she goes to school the next day, and even though She has the correct Answer and all the steps, the teacher proceeds to ask her, What is (gf)(x)? With your limited explanation, she may not be able to answer the teacher's question.

Best ResponseYou've already chosen the best response.0@Hero Hi ... I certainly wasn't intending to stop there! But, there was no one in sight ... evidently the user had gone offline. What is the recommendation at that point? Should you then type out the complete answer? I know the code of honor is certainly NOT just to give the answer...

Best ResponseYou've already chosen the best response.0What gm trying to suggest here is to Compute (gf)(x) first before computing (gf)(2)

Best ResponseYou've already chosen the best response.0When you see \(g(x) = 2x  3\), it's what is called "function notation". Think of it this way: g(blah) = 2(blah)  3. So: g(1) = 2(1)  3 g(2) = 2(2)  3 g(10.7) = 2(10.7)  3 Are you seeing the pattern?
