Question 383538
{{{f(x)=sqrt(x-2)}}}
You can generate the squares in your head.
When {{{x=0}}}, {{{x^2=0}}}, and {{{sqrt(0)=0}}}
When {{{x=1}}}, {{{x^2=1}}}, and {{{sqrt(1)=1}}}
When {{{x=2}}}, {{{x^2=4}}}, and {{{sqrt(4)=2}}}
When {{{x=3}}}, {{{x^2=9}}}, and {{{sqrt(9)=3}}}
When {{{x=4}}}, {{{x^2=16}}}, and {{{sqrt(16)=4}}}
When {{{x=5}}}, {{{x^2=25}}}, and {{{sqrt(25)=5}}}
So then when {{{x-2=0}}}, {{{x=2}}}, {{{sqrt(x-2)=0}}}

{{{x-2=1}}}, {{{x=3}}}, {{{sqrt(x-2)=1}}}
{{{x-2=4}}}, {{{x=6}}},{{{sqrt(x-2)=2}}}
{{{x-2=9}}}, {{{x=11}}},{{{sqrt(x-2)=3}}}
{{{x-2=16}}},{{{x=18}}}, {{{sqrt(x-2)=4}}}
{{{x-2=25}}},{{{x=27}}},{{{sqrt(x-2)=5}}}

Plot those points and connect the points with lines.
