Evaluate the function for
f%28x%29+=+x+%2B+3
and
g%28x%29+=+x%5E2+%E2%88%92+2
%28f+%2B+g%29%285%29
first find %28f+%2B+g%29%28x%29
%28f+%2B+g%29%28x%29=x+%2B+3%2Bx%5E2+%E2%88%92+2
%28f+%2B+g%29%28x%29=x%5E2+%2Bx%2B1
now find
%28f+%2B+g%29%285%29=5%5E2+%2B5%2B1
%28f+%2B+g%29%285%29=25+%2B5%2B1
%28f+%2B+g%29%285%29=31
