Question

Write a rule that represents the function (0,0) (1,2) (2,8) (3,18) (4,32). Please help!

Answer 1

y=2x^2 
or y equals 2x to the 2nd power.

Answer 2

$\bf \begin{array}{ccllll} x&y\\ ------&------\\ 0&\stackrel{0^2\cdot 2}{0}\\\\ 1&\stackrel{1^2\cdot 2}{2}\\\\ 2&\stackrel{2^2\cdot 2}{8}\\\\ 3&\stackrel{3^2\cdot 2}{18}\\ 4&\stackrel{4^2\cdot 2}{32}\\\\ x&\stackrel{x^2\cdot 2}{2x^2} \end{array}$
