Question 1001744




{{{x}}}|{{{y}}}

{{{1}}}|{{{3.2}}}=>{{{3.2=3.2*1}}}=>{{{3.2=3.2*1^2}}}
{{{2}}}|{{{12.8}}}=>{{{12.8=3.2*4}}}=>{{{12.8=3.2*2^2}}}
{{{3}}}|{{{28.8}}}=>{{{28.8=3.2*9}}}=>{{{28.8=3.2*3^2}}}
{{{4}}}|{{{51.2}}}=>{{{51.2=3.2*16}}}=>{{{51.2=3.2*4^2}}}
{{{5}}}|{{{80}}}=>{{{80=3.2*25}}}=>{{{80=3.2*5^2}}}

so, we have {{{y=3.2x^2}}}

your answer is:
c. {{{y}}} is proportional to {{{x^2}}}
