Question

9. Factorize: a2 - 9​

Answer 1

Answer:

Correct option is

A

D:x∈RR:[0,2]

$$y = \log_\sqrt{5} (\sqrt{2} (\sin  x - \cos x) + 3)$$

We know,  −2≤sinx−cosx≤2

Hence domain is x∈R

and Range $$[\log_\sqrt{5} (\sqrt{2} (-\sqrt{2}), \log_\sqrt{5} (\sqrt{2} (\sqrt{2}) + 3)]=[\log_\sqrt{5}1, \log_\sqrt{5} 5] = [0,2]$$
