Answer
1st step (black graph): The parent function: $y=\sqrt x$
2nd step (green graph): Flipped over the y-axis. $y=\sqrt{-x}$
Final step (blue graph): Shift 1 unit to the right: $y=\sqrt{1-x}$
The x-intercept is (1,0)
The y-intercept is (0,1)
The domain is $(-\infty,1]$
The range is $[0,\infty)$
Work Step by Step
The x-intercepts are all points of a graph when f(x)=0 while the y-intercepts are all points of a graph when x=0.
The domain is a horizontal span from the function's smallest value of x to the function's largest value of x.
The range is a vertical span from the function's smallest value of f(x) to the function's largest value of f(x).
