Question

What is the domain and range of the quadratic equation y= (x-5)^2 + 10?

1) range= y≥5
2) range= y≤5
3) range= y≥10
4) range= y≤10

Answer 1

since the first term is always non-negative the range is
\[y\geq10\]

Answer 2

by "first term" i mean
\[(x-5)^2\] which, since it is a square, is always greater than or equal to zero
