Answer: [tex]\text{f(a+2)}=3a+6+\dfrac{5}{a+2}[/tex]
Step-by-step explanation:
The given function: [tex]f(x)=3x+\dfrac{5}{x}[/tex]
To find the value of [tex]\text{f(a+2)}[/tex], we need to replace the value of x by a+2, we get
[tex]f(x)=3(a+2)+\dfrac{5}{a+2}\\\\\Rightarrow\ \text{f(a+2)}=3a+6+\dfrac{5}{a+2}[/tex]
Hence, the value of [tex]\text{f(a+2)}[/tex] is given by :_
[tex]\text{f(a+2)}=3a+6+\dfrac{5}{a+2}[/tex]
