If f’ (1) = 2 and y = f(log_e x), find .. at x = e.

y = f(log_ex)

Using the Chain Rule of Differentiation,

So, at x = e

(Ans)

If f(x) = log_e (log_e x), then write the value of f’(e).

If f(x) = x + 1, then write the value of

If f(1) = 4, f’(1) = 2, find the value of the derivative of log (f(e^x)) with respect to x at the point x = 0.

If and y = f(x²), then find at x = 1.

If f’ (1) = 2 and y = f(loge x), find .. at x = e.
