Vedclass · Answer

(B) Given function: $y(x) = \cos x - 3$. Since the domain of $\cos x$ is the set of all real numbers $R$,the domain of $y(x)$ is $R$. We know that for any $x \in R$,$-1 \leq \cos x \leq 1$. Subtracting $3$ from all parts of the inequality: $-1 - 3 \leq \cos x - 3 \leq 1 - 3$ $-4 \leq y(x) \leq -2$. Thus,the range of the function is $[-4, -2]$. Therefore,the domain is $R$ and the range is $[-4, -2]$.

The domain and range of $y(x) = \cos x - 3$ are respectively
