What is the domain of y=/x+7 +5?
x>=0
x>=7
X>=-7
all real numbers
DONE

Step-by-step explanation:

when x >0

y=/0+7 +5

y=8

(0,8)

when x>7

y= /7+7 +5

y= 9

(7,9)

when x >-7

y = /7-7 +5

y=5

(-7, 5)

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
