Consider f, a function such as f(2) = 1, f'(2) = 2, f''(2) = 3 and f'''(2) = 4 and that verifies: -3 < f(x) < 34 0 < f'(x) < 12 -8 < f''(x) < 9 -6 < f'''(x) < 5 for all x ∈ [0,4]. Find the second degree Taylor polynomial, T2(x), of f at a = 2, then use T2(x) to approximate f(1) and determine a bound on the approximation error. Give a bound on the approximation error f(x) ≈ T2(x) that is valid for all x in the interval [0,4].

Consider f, a function such as f(2) = 1, f'(2) = 2, f''(2) = 3 and f'''(2) = 4 and that verifies:
-3 < f(x) < 34
0 < f'(x) < 12
-8 < f''(x) < 9
-6 < f'''(x) < 5 for all x ∈ [0,4].
Find the second degree Taylor polynomial, T2(x), of f at a = 2, then use T2(x) to approximate f(1) and determine a bound on the approximation error.
Give a bound on the approximation error f(x) ≈ T2(x) that is valid for all x in the interval [0,4].
-------
I was able to find T2(x) = 1 + 2(x-2) + 3/2(x-2)2 and the approximation f(1) ≈ 1/2, but I don't understand how to find the approximation error bounds? Are we supposed to use Taylor's inequality definition?
