The RANGE of this function is
A) [1, 5]
B) [3, ∞)
C) [-4, ∞)
D) (-∞, ∞)

y = (x - 1)(x - 5) -> polinom

Range = (-∞, ∞) (D)

I think it is C.

Step-by-step explanation:

You can't really have negative infinity because the parabola doesn't go down forever. It only goes up on both sides.

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
