Question

Given the function k described by k(x) = 3x, find each of the following.(a) k( - 11)(b) k(10)(c) k(30)k(-11)=k(10) =k(30)=

Answer 1

the initial function is:

$k(x)=3x$

So we can evaluate in the following numbers so:

$\begin{gathered} k(-11)=3(-11)=-33 \\ k(10)=3(10)=30 \\ k(30)=3(30)=90 \end{gathered}$
