Question 642841
{{{f(x)= x^2- 9 }}}...

to graph it, first make a table, choose several values for {{{x}}}, calculate {{{f(x)}}} to get points, plot these points and draw a graph:


{{{x}}}|{{{f(x)}}}

{{{0}}}|{{{-9}}}

{{{1}}}|{{{-8}}}

{{{-1}}}|{{{-8}}}

{{{2}}}|{{{-5}}}

{{{-2}}}|{{{-5}}}

{{{3}}}|{{{0}}}

{{{-3}}}|{{{0}}}




{{{ graph( 600, 600, -10, 10, -10, 10, x^2- 9) }}}
