Left is plus right is negative -11-(-15)=4 so you know 4 to the left

we have

$y=2(x-15)^{2}+3$

this is the equation of a vertical parabola open up with vertex at point $(15,3)$

$y=2(x-11)^{2}+3$

this is the equation of a vertical parabola open up with vertex at point $(11,3)$

so

the rule of the translation is

$(x,y)---------> (x-4,y)$

that means

the translation is $4$ units to the left

therefore

<u>the answer is</u>

$4$ units to the left
