Question

a. Express the rule “cube n, then multiply by 23” as the function f(n) = b. Express the rule “multiply by 23, then cube” as the function f(n) =

Answer 1

`\begin{gathered} a\text{. }f(n)=n^3\cdot23 \\ b\text{. }f(n)=(23\cdot n)^3 \end{gathered}`

Explanation:

We calculate the function in each case starting from what is written in the statement, like this:

(a)

`f(n)=n^3\cdot23`

(b)

`f(n)=(23\cdot n)^3`
