The function is always increasing.
The function has a domain of all real numbers.
The function has a range of {y-00 << o }
The function is a reflection of y =
x.
The function passes through the point (3.-27).

Answer 1

Explanation:

"The function is always increasing" is false. The function is always decreasing.

"The function has a domain of all real numbers." True. The function is a polynomial and thus has a domain of all real numbers.

"The function has a range of {y-00 << o }." False. The range is (-∞, ∞ ).

"The function is a reflection of y = x." True

"The function passes through the point (3.-27)." False
