I need help determining the rang of this graph

The highest point is when y = 0 and the lowest point is when y = -5

We can see this if we draw horizontal lines through the highest and lowest points (see the diagram below). Note where the horizontal lines cross the y axis. For y = 0, we don't really need a horizontal line but I'll draw it anyway.

Since y ranges from y = -5 to y =0, the range is therefore

Side note: to write this in interval notation, you would say . The square brackets say to include each endpoint as part of the range.

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
