Question

What is the range of the graph of y = (x – 4)2 + 1?

Answer 1

The smallest value that (x - 4)^2 can be is 0 because it is "something squared", so the smallest that the right side can be is "1".

So, the range is [1, infinity)

Answer 2

Also, this is a parabola opening upwards. It has a low point of y = 1. The range refers to the y values.

Answer 3

–2 ± i

–2 ± 2i

–1 ±i

1 ± i
