How to determine if an ordered pair is a solution

Mathematics
1 answer:
levacccp [35]3 years ago

Plug in the point and if the point gives 2 true statements for each equation, then it is a solution.  Plugging in (-3,6) does not create a true statement for the second equation, so it is not a solution.

The point (3,2) works for both equations, so it is a solution.

lord [1]

Answer:

6 and 7

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x) , that is

f(3) = 2(3) = 6

To evaluate g(f(3)), substitute f(3) = 6 into g(x)

g(6) = 6 + 1 = 7
