The function f(x) = −(x + 5)(x + 1) is shown. on a coordinate plane, a parabola opens down. it goes through (negative 5, 0), has a vertex at (negative 3, 4), and goes through (negative 1, 0). 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

The range is all real numbers less than or equal to 4

Step-by-step explanation:

we have

This is a vertical parabola open downward

The vertex is a minimum

The vertex is the the point (-3,4)

The x-intercepts are x=-5, x=-1

The domain is the interval -----> (-∞,∞)

The domain is all real numbers

The range is the interval ----> (-∞, 4]

The maximum value of the range is the y-coordinate of the vertex

The range is all real numbers less than or equal to 4

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
