Question 1084617
{{{ y^2 = 12x }}}
{{{ y = ( 12x )^(1/2) }}}
{{{ y[1] = (1/2)* ( 12x )^(-1/2)*12 }}}
{{{ y[1] = 6*( 12x )^(-1/2) }}}
at (3,6)
{{{ y[1] = 6*( 12*3)^(-1/2) }}}
{{{ y[1] = 6/sqrt(36) }}}
{{{ y[1] = 6/6 }}}
{{{ y[1] = 1 }}}
--------------------
Here are plots of {{{ y }}} and {{{ y[1] }}}
{{{ graph( 500, 500, -2, 10, -2, 10, (12x)^(1/2), 6*( 12x )^(-1/2) ) }}}
