Problem

Given the functions below, find $(g+h)(1)$. \[ \begin{array}{l} g(x)=x^{2}+4+2 x \\ h(x)=-3 x+2 \end{array} \] 12 $-6$ 6 8

Solution

Step 1 :Given the functions \(g(x)=x^{2}+4+2x\) and \(h(x)=-3x+2\), we are asked to find the value of \((g+h)(1)\). This means we need to find the sum of the functions \(g(x)\) and \(h(x)\) at \(x=1\).

Step 2 :First, we find the value of \(g(1)\) by substituting \(x=1\) into the function \(g(x)\). This gives us \(g(1)=1^{2}+4+2(1)=7\).

Step 3 :Next, we find the value of \(h(1)\) by substituting \(x=1\) into the function \(h(x)\). This gives us \(h(1)=-3(1)+2=-1\).

Step 4 :Finally, we add these two values together to get the final answer. This gives us \((g+h)(1)=g(1)+h(1)=7+(-1)=6\).

Step 5 :So, the value of \((g+h)(1)\) is \(\boxed{6}\).
