Ex 6.5, 2 Find the maximum and minimum values, if any, of the following functions given by (i) 𝑓 (𝑥)=|𝑥 + 2| –1 𝑓 (𝑥)=|𝑥 + 2| –1 Minimum value of |𝑥 + 2|=0 Minimum value of f(𝑥)= minimum value of |𝑥 + 2| –1 =0−1 =−1 Hence minimum value of f(𝒙)=−𝟏 And there is no maximum value of f(x)

Next: Ex 6.5, 2 (ii) Important → Ask a doubt
