I don’t see the graphs — could you upload or list the answer choices?
Meanwhile, here’s how to pick the correct graph: the graph must have its lowest y-value equal to −1 and then include every y above that (no y-values below −1). Common examples that have range [−1, ∞) are:
- An upward parabola with vertex at (0, −1) (e.g. y = x^2 − 1).
- A V-shaped absolute-value graph with vertex at (0, −1) (y = |x| − 1).
- A square-root curve starting at (0, −1) and increasing to the right (y = √x − 1).
Make sure to reject graphs that dip below −1 or that approach −1 but never reach it (e.g. y = e^x − 1 has range (−1, ∞), not including −1). Upload the images or options and I’ll point to the exact one.
