- A 2.0512
- B 2.0425
- C 2.0625
- D 2.0834
Answer & Solution
Correct Answer
(C) 2.0625
Step-by-step Solution
Detailed explanation
Let \(y=f(x)=x^{1 / 4}\) and \(x=16\) and \(\Delta x=2\) So, \(\Delta y=\left(\frac{d y}{d x}\right) \Delta x=\frac{1}{4}\left(x^{-3 / 4}\right) \Delta x\) at \(\quad x=16\) and \(\Delta x=2\)…
