Question

find the range
f(x) = (x - 2)2 + 2
A. all real numbers
B. y greater than or equal to 0
C. y less than 2
D. y greater than or equal to 2

Answer 1

The range is all of the y-values. So, you can graph the function and see what happens to the y-values.... where they start/end (if they even terminate or not)
