Does this graph represent a function? What is the domain and range of the graph? Yes; domain: all real numbers; range: y = 0
Yes; domain: all real numbers; range: y 2 0
No; domain: all whole numbers; range: y SO
Yes; domain: all real numbers; range: y > 0

Yes; domain: all real numbers; range: y 0

Step-by-step explanation:

1. Use the vertical line test to see if it is a function.

2. Figure out what the lowest and highest point x can be. In this case x can be any number

3. Figure out what the lowest and highest point of y can be. In this case y is not negative, the lowest it can be is 0. So y 0

*Note: Domain are the x values & Range are the y values

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
