Ex 6.5, 2 Find the maximum and minimum values, if any, of the following functions given by (iv) 𝑓 (𝑥)=|sin4𝑥+3|𝑓 (𝑥)=| sin4𝑥+3| We know that –1 ≤ sin θ ≤ 1 So, –1 ≤ sin 4𝑥 ≤ 1 Adding 3 both sides –1 + 3 ≤ sin 4𝑥 + 3 ≤ 1 + 3 2 ≤ sin 4𝑥 +3 ≤ 4 Taking modulus |2| ≤ | sin4𝑥+3| ≤ |4| 2 ≤ | sin4𝑥+3| ≤ |4| 2 ≤ f(𝑥)≤4 Hence Maximum value of f(𝒙) is 4 & Minimum value of f(𝒙) is 2
