Question 1173810
<pre>
The equation {{{f(x)=y=sqrt(x)}}} has this graph: 

{{{graph(200,3200/43,-2.9,10,-.9,3.9,sqrt(x))}}}

To shrink it horizontally by 1/3, we multiply the right side by the reciprocal of
1/3, which is 3.  So the equation is {{{y=3sqrt(x)}}} which has this graph:

{{{graph(2400/17,3200/43,-2.9,3.9,-.9,3.9,3sqrt(x))}}}

To translate it horizontally by 2 units left, we replace x in the right side by
(x+2).  So the equation is {{{y=3sqrt(x+2)}}} which has this graph:

{{{graph(2400/17,3200/43,-2.9,3.9,-.9,3.9,3sqrt(x+2))}}}

Answer:  {{{y=3sqrt(x+2)}}}
