Sure, let's solve this step by step:

1. First, we need to find the value of f(4). The function f(x) is given as x^2 + 1. So, replace x with 4 in the function: f(4) = (4)^2 + 1 = 16 + 1 = 17.

2. The problem asks for 2·f(4), so we multiply the result from step 1 by 2: 2·f(4) = 2 * 17 = 34.

So, 2·f(4) = 34.
