I don't understand this and I would love to learn how to do this:
Consider the function g:
{(2, 7), (4, 9), (12, 19), (20, 27), (31, 38)}
What is g (12)?

Best ResponseYou've already chosen the best response.6You put the x value into the function, the y value comes out.

Best ResponseYou've already chosen the best response.6Do you see how that might work with the 12? the 12 is corresponding to x=12

Best ResponseYou've already chosen the best response.0so for (2, 7) g would be 3.5?

Best ResponseYou've already chosen the best response.6No, it's not g `times` 2. function notation takes a little getting used to I guess :) hehe. It's the function g, at a specific moment in time or place. The 2 is connected to the g in that way. so we would say that g `of` 2 equals 7. g=7 for that particular x value

Best ResponseYou've already chosen the best response.0ooh I always thought of it as times xD sorry so G would be 2 at a certain time and would that would equal 7?

Best ResponseYou've already chosen the best response.6you put 2 INTO the g function and 7 comes out.

Best ResponseYou've already chosen the best response.0omg soo much clearer now xD so I need to find what goes into g that comes out 12?

Best ResponseYou've already chosen the best response.0so ima give it a shot, please correct me if im wrong lol, The answer is 7? 7 goes into g to make 12?

Best ResponseYou've already chosen the best response.0ok before I answer, does the function provide the answer? like (12,19)

Best ResponseYou've already chosen the best response.6yes, the ordered pair is written like this, (input, output)

Best ResponseYou've already chosen the best response.6ok good job \c:/ so when x=12 goes INTO the function g(x), then 19 comes OUT of it. so therefore g(12) = 19
