Answer:

Easy way to distinguish:

  • Linear function forms a AP and exponential function forms a GP

We see f(x) is series of:

  • 8, 14, 20, 26, 32
  • This is a AP with common difference of 6 and the first term of 8

g(x) is series of:

  • 4, 12, 36, 108, 324
  • This is a GP with common ratio of 3 and the first term of 4

1. g(x) is exponential function:

  • g(x) =4*3ˣ

2. f(x) is linear function:

  • f(x) = 6x + 8
