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

They give you a graph so this will be easy. What I do is imagine shading going back to the y-axis from the graph. This is how to get a visual of the range.

Since the shading would go from 4 all the way to negative infinity, the answer is all real numbers less than or equal to 4.

Best of luck!

Something that is true about that is that it has numbers
