If \(f(x)=x+1\), \(g(x)=2x\), and \(h(x)=x^2\), what is the value of \((h\circ g\circ f)(1)\)?

Answer and explanation

Correct answer: 16

The composite function \((h\circ g\circ f)(x)=h(g(f(x)))\), so the functions must be applied from right to left. First, \(f(1)=1+1=2\); then \(g(2)=2\times2=4\); finally, \(h(4)=4^2=16\). Therefore, the correct answer is 16. Option 8 results from reversing the order of \(g\) and \(h\), while 4 is obtained by stopping after the second step. Exam tip: in a function composition, apply the rightmost function first.
