F the function () represents the number of hours that it takes a person to catch fish in a lake. What domain makes sense for the function? 1 point

−[infinity] ≤ ≤ [infinity]

0 < < [infinity]

≤ 0

≥ [infinity]

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

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

the answer should be a. snail
