a)![\mathbf{ f(g(x))=x+2\sqrt{x} +1}](/tpl/images/1020/5469/0fd49.png)
b)![\mathbf{f(g(9))=16}](/tpl/images/1020/5469/2f39b.png)
Step-by-step explanation:
We are given:
We need to find![a) f(g(x))\\b) f(g(9))](/tpl/images/1020/5469/15bfc.png)
a) First finding:![f(g(x))](/tpl/images/1020/5469/3a091.png)
It can be found by putting the value of g(x) into f(x)
We are given:
SO, we get:![\mathbf{ f(g(x))=x+2\sqrt{x} +1}](/tpl/images/1020/5469/0fd49.png)
b) Now finding:![f(g(9))](/tpl/images/1020/5469/c9d32.png)
It can be found by putting x=9 in f(g(x))
We have:
So, we get:![\mathbf{f(g(9))=16}](/tpl/images/1020/5469/2f39b.png)
