The function f(x) = −(x + 5)(x + 1) is shown. what is the range of the function? all real numbers less than or equal to 4 all real numbers less than or equal to −3 all real numbers greater than or equal to 4 all real numbers greater than or equal to −3

ANSWER

all real numbers less than or equal to 4.

EXPLANATION

The given function is

Expand

a=-1,b=-6,c=-5

The x-value of the vertex is given by

a=-1,b=-6,c=-5

The y-value of the vertex is

Since a=-1, the function opens downwards.

The highest value is the y-value of the vertex which is 4.

Therefore the range is all real numbers less than or equal to 4.

The correct choice is A.

i believe the correct answer is b.
