Problem
Let $f(x)=4 x-1, h(x)=-x+2$ Find $(h \circ f)(1)$.
Solution
Step 1 ：Let \(f(x)=4 x-1\), \(h(x)=-x+2\). We need to find \((h \circ f)(1)\).
Step 2 ：First, we find the value of \(f(1)\).
Step 3 ：Substitute \(x = 1\) into \(f(x)\), we get \(f(1) = 4*1 - 1 = 3\).
Step 4 ：Then, we substitute this value into \(h(x)\).
Step 5 ：Substitute \(x = 3\) into \(h(x)\), we get \(h(3) = -3 + 2 = -1\).
Step 6 ：So, \((h \circ f)(1) = -1\).
Step 7 ：Final Answer: \(\boxed{-1}\)
