The function f(x) = −(x + 5)(x + 1) is shown.

what is the range of the function?

a. all real numbers less than or equal to 4
b. all real numbers less than or equal to −3
c. all real numbers greater than or equal to 4
d. all real numbers greater than or equal to −3

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
