What is the range of the function?

[0, ∞ )

Step-by-step explanation:

f(x) = (x - 3)²

Because of the squaring function, f(x) can never be negative, altho' it can be zero (0) at x = 3.  Thus, the range is [0, ∞ ).

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
