### Access answers to Maths RD Sharma Solutions For Class 12 Chapter 15 – Mean Value Theorems Exercise 15.1 Important Questions With Solution

**1. Discuss the applicability of Rolle’s Theorem for the following functions on the indicated intervals:**

**Solution:**

**(ii) f (x) = [x] for -1 ≤ x ≤ 1, where [x] denotes the greatest integer not exceeding x**

**Solution:**

**Solution:**

**(iv) f (x) = 2x ^{2} – 5x + 3 on [1, 3]**

**Solution:**

Given function is f (x) = 2x^{2} – 5x + 3 on [1, 3]

Since given function f is a polynomial. So, it is continuous and differentiable everywhere.

Now, we find the values of function at the extreme values.

⇒ f (1) = 2(1)^{2}–5(1) + 3

⇒ f (1) = 2 – 5 + 3

⇒ f (1) = 0…… (1)

⇒ f (3) = 2(3)^{2}–5(3) + 3

⇒ f (3) = 2(9)–15 + 3

⇒ f (3) = 18 – 12

⇒ f (3) = 6…… (2)

From (1) and (2), we can say that, f (1) ≠ f (3)

∴ Rolle’s Theorem is not applicable for the function f in interval [1, 3].

**(v) f (x) = x ^{2/3} on [-1, 1]**

**Solution:**

**Solution:**

**2. Verify the Rolle’s Theorem for each of the following functions on the indicated intervals:**

**(i) f (x) = x ^{2} – 8x + 12 on [2, 6]**

**Solution:**

**(ii) f(x) = x ^{2} – 4x + 3 on [1, 3]**

**Solution:**

**(iii) f (x) = (x – 1) (x – 2) ^{2} on [1, 2]**

**Solution:**
