Question
Graph each equation in a standard viewing window.$$y=-2 \sqrt{x+5}$$
Step 1
The inside x+5 shifts the graph left 5 units, and the factor -2 multiplies outputs by 2 and reflects across the x-axis. So domain: x ≥ -5; range: y ≤ 0. The starting point (vertex) is at x = -5 giving (-5, 0). Show more…
