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.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
