Question

h(x)=4x^2-5x+1, K(x)=x and m(x)=7 for all x.
compute h[k(x)]. What do the brackets mean??

Answer 1

It means that function h maps function k which maps x onto.........

Answer 2

Answer 3

Errr... For this one, k(x)=x so you need not change anything in hk(x) cause it's the same.
h[k(x)]=h(x) as x=k(x)
