By first principle, Find the derivative of the function

iii.) f(x) = 3x^2 + 2x + 1

with respect to x at x = x subscript 0

And using the result, find the value of y at :

X_0 = 2

X_0 = 1/2

X_0 = 0

To find the derivative of the function f(x) = 3x^2 + 2x + 1 with respect to x, we take the derivative of each term separately.

f'(x) = d/dx (3x^2) + d/dx (2x) + d/dx (1)
= 6x + 2

Now, to find the value of the derivative at x = x_0, we substitute x_0 into f'(x):

f'(x_0) = 6(x_0) + 2

a) When x_0 = 2:
f'(2) = 6(2) + 2 = 12 + 2 = 14

b) When x_0 = 1/2:
f'(1/2) = 6(1/2) + 2 = 3 + 2 = 5

c) When x_0 = 0:
f'(0) = 6(0) + 2 = 0 + 2 = 2

Therefore, the values of the derivative at x_0 = 2, x_0 = 1/2, and x_0 = 0 are 14, 5, and 2 respectively.
