just choose three x values and calculate the corresponding y-values. say you choose x = 1, x = 2, and x = 3, then your points are: (1,f(1)), (2,f(2)), and (3,f(3))
For f(x) coordinates I have (1,2), (2,4), and (3,8)...what will the coordinates be for g(x)=3*2^(x+4)-1, if I use 1, 2, and 3 for the x-value????
um, you tell me. you'd get them exactly the same way you got the values you just told me, which were right by the way. same procedure. namely, the points would be (1,g(1)), (2,g(2)), and (3,g(3)). are you getting the idea of what we are doing here?
