Question

What is the domain and range of `y = (x – 5)^2 + 10`?

Answer 1

Domain is all of `RR`, `(-oo,+oo)`
Range `[10, oo)`

Explanation:

This is a quadratic function, representing a vertical parabola, opening up with its vertex at (5,10). This makes it obvious that domain is all of `RR` that is `(-oo,+oo)` and Range is `[10,+oo)`
