Question 99852
The graph {{{y=sqrt(x)}}} looks like this



{{{ graph( 500, 500, -10, 10, -10, 10, sqrt(x)) }}} Graph of {{{y=sqrt(x)}}} 




So if you negate the x to get {{{y=sqrt(-x)}}} it flips the graph 




{{{ graph( 500, 500, -10, 10, -10, 10, sqrt(-x)) }}} Graph of {{{y=sqrt(-x)}}} 




Now when you add 5 to -x you get {{{y=sqrt(5-x)}}} which shifts the graph 5 units to the right




{{{ graph( 500, 500, -10, 10, -10, 10, sqrt(5-x)) }}} Graph of {{{y=sqrt(5-x)}}}
