Answer:

We are given:

f(1) = 8

f'(1) = 3

f''(1) = 4

Using these conditions, we can write three equations:

f(1) = a(1)^2 + b(1) + c = 8

f'(1) = 2a(1) + b = 3

f''(1) = 2a = 4

Simplifying the last equation, we get:

2a = 4

a = 2

Substituting this value of a in the second equation, we get:

2(1) + b = 3

b = 1

Substituting the values of a and b in the first equation, we get:

2(1)^2 + 1(1) + c = 8

c = 5

Therefore, the values of a, b, and c are:

a = 2

b = 1

c = 5

Hence, f(x) = 2x^2 + x + 5.
