Question

PLEASE HELP ASAP !!!!


Which functions have a range of {y e R-00 < y < ∞0}?
O f(x) = -4x + 11
Of(x) = x - 8
O
f(x) = 2x+3
O f(x) = -(x + 1)² - 4
O
f(x)
f(x) = x²
x² + 7x9

2. Correct. The range of all linear functions without a restricted domain is the set of all real numbers.
3. Wrong. The exponential cannot take negative values.
4. Wrong. Quadratics do not have a range that is the set of real numbers.
5. Wrong. Quadratics do not have a range that is the set of real numbers.
