Answer
1st step (black graph): The parent function: $y=|x|$
2nd step (green graph): Flipped on the x-axis. $y=-|x|$
3rd step (blue graph): Stretched by a factor of 2. $y=-2|x|$
The x-intercept is (0,0)
The y-intercept is (0,0)
The domain is $(-\infty,\infty)$
The range is $(-\infty,0]$
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).
