A) \[{{R}^{+}}\]
B) \[R-\{0\}\]
C) \[[1,\,\,\infty )\]
D) \[{{R}^{+}}-\{1\}\]
Correct Answer: C
Solution :
Let \[f\] image of \[goh\] image,\[fogoh=F(x)=f[goh(x)]\] \[F(x)=\frac{2}{\cos \sqrt{x+3}+1}\] Now\[x+3\ge 0\]and\[-1<\cos \sqrt{x+3}\le 1\] \[\sqrt{x+3}\ne (2n-1)\pi ,\,\,n\in N\]You need to login to perform this action.
