WebWe are told that h of x is equal to 3x. g of t is equal to negative 2t minus 2 minus h of t. f of n is equal to negative 5n squared plus h of n. So we have three function definitions, and two of these function definitions are actually defined in terms of another function-- in particular, in terms of the function h.
