∆y/∆x = 2
f(x) = 2x+3
None of the g(x) matches for x=3
Find f(3) for the function in the Table.
| x | -4 |-1| 0 | 2 |
|f(x)| -5 | 1 | 3 | 7 |
Now check the equations below. Which of them has g(3) = the f(3) you just found?
a) g(x) = 5x - 6
b) g(x) = 2x + 5
c) g(x) = 3x - 7
d) g(x) = 4x - 1

oops. I did not calculate f(3).
I'm sure you did, though.
