Let f(x) and g(x) be two functions. The composite function \(\displaystyle{f}\circ{g}\) can be calculated using the following steps:
1. Evaluate the value of inside function at the given point.
2. Then, take the resultant output as the input to outside function.
Here, \([email protected][email protected] (x)=f(g(x))\)
Let us assume that the value of function g at point x is \(g(x)=t\) where t is some constant
So, \(f(g(x))=f(t)\)
Let us assume that the value of f at point t is \(f(t)=u\), where u is some constant. In this way, composite function can by evaluated.
