How do you find s[h(x)] if #s(x) = 2^x# and #h(x) = x^2#? Precalculus Functions Defined and Notation Function Composition 1 Answer mason m Jan 4, 2016 #s(h(x))=2^(x^2)# Explanation: #s(h(x))# is a way of saying put #h(x)# in #s(x)#. In other words, take #x^2#, and plug it in the spot where #x# is in #2^x#. #s(h(x))=2^(x^2)# Answer link Related questions What is function composition?
