Question

Please please help me ASAP

Answer 1

Given:

`f(x)=(1)/(x)\colon g(x)=x^2+5x`

so (f.g)(x) is:

`fg(x)=(1)/(x^2+5x)`

Domain: domain is define as a all possible input where function is define is know as a domain of function.

`\text{Domain}=\text{ x}\in R\colon x\\e5\text{ and x}\\e0`

Range: range is define as a output of function

and the function output is:

so the range of function is

`\text{Range y}\in R\colon y\leq(-4)/(25)\text{ or }y>0`
