1. Start with the initial condition:

f(0) = 6

2. Use the recurrence relation to find f(1), letting x=0:

f(1) = 2f(0) - 5 = 2 \cdot 6 - 5 = 12 - 5 = 7

3. Use the recurrence relation again to find f(2), letting x=1:

f(2) = 2f(1) - 5 = 2 \cdot 7 - 5 = 14 - 5 = 9

Thus, the value of f(2) is:

f(2) = 9
