Question

g(n) = n
2+ 4 + 2n
h(n) = −3n + 2
Find (g ⋅ h)(1)

Answer 1

First, what do you mean by typing 2 + 4 + 2n with no equal sign?
If function g(n) = n and function h(n) = -3n + 2, then (g * h)(n) = (n)*(-3n + 2). (Multiply that out, if you wish.) Then, substitute 1 for n and evaluate the result.
