Best ResponseYou've already chosen the best response.0let's pretend with have a linear equation and lets say (2,5) and (0,5) lie on this line. so the slope is {5(5)}/{0(2)}=10/2=5 so we have y=5x+b and we know a point on this line (0,5) so we have 5=0+b so the y intercept b=5 so the equation of the line through those two points are y=5x+5 so let g(x)=5x+5 g(2)=5(2)+5=10+5=5 if x=2 then g(2*(2))=5(2)+5=10+5=5 so (4,5) yes you are right it only affects the x

Best ResponseYou've already chosen the best response.0You know that (2,5) is on the graph of g(x). So, what about the point g(2(1)). Plug x=1 on the function g(2x), you get g(2(1))=g(2)=5. Hence (1,5) is a point on the graph of g(2x).

Best ResponseYou've already chosen the best response.0Another way to see that, is by looking at the function g(2x). You can see that only values of is affected. Set 2x=2 and solve for x, you get x=1, which is the same value we got above. S again (1,5) is a point on g(2x).
