Answer 1

Question-

My answer-

Answer 2

what my teacher said was wrong- "incorrect"

Answer 3

the x^2 has a minimum value of 0 (x^2 cannot be negative)

but with the -5 that makes the minimum value -5

Answer 4

so the range is [-5,b) - what would b be?

Answer 5

x^2 could be any number greater than 0.....

Answer 6

So the range would be 0 to infinity?
