NCERT EXERCISE 6.5 |

Question 1. Find the maximum and minimum values, if any, of the following functions given by

(i) f(x) = (2x - 1)^2 + 3

(ii) f(x) = 9x^2 + 12x + 2

(iii) f(x) = -(x - 1)^2 + 10

(iv) g(x) = x^3 + 1

Question 2. Find the maximum and minimum values, if any, of the following functions given by

(i) f(x) = |x + 2| - 1

(ii) g(x) = - |x + 1| + 3

(iii) h(x) = \sin (2x) + 5

(iv) f(x) = |\sin 4x + 3|

(v) h(x) = x + 1, x \in (-1, 1)
