Transformed #f(x) = -(sqrtx+3)#

Explanation:

First consider the "parent" graph #f(x)=sqrtx# shifted 3 unit positive ("up") on the #y-#axis. This will be the function #f(x)+3# so the first transformation #f_1(x) = sqrtx+3# and is shown in the graph below.

graph{sqrtx+3 [-20.27, 20.27, -10.13, 10.14]}

To reflect this function in the #y-#axis we simply replace it by its negative. So #f_2(x) = -f_1(x) = -(sqrtx+3)# shown in the graph below.

graph{-(sqrtx+3) [-20.27, 20.27, -10.13, 10.14]}

Hence, our transformed #f(x) = -(sqrtx+3)#
