Question

If
f(x) = x^2+1 find f'(2) from
first principle
.​

Answer 1

Answer:

If f(x) = x² + 1, find f'(2) from the first.principle. f(x) = x² + 1 to find the value of f'(2), first we need to find f'(x) f'(x) = 2x Now to find value of f'(2) , we need to put x = 2 in f'(x) putting x= 2 f'(x) = 2x f'(2) = 2 * 2 => f'(2) = 4 %3D f'(2) = 4 if f(x) = x² +1
