Based on the graph of the function which of the following statements are true?

on the interval

on the interval

on the interval

on the interval

Step-by-step explanation:

Remember that . When the graph of the function is below the x-axis, the value of is negative; therefore the function is less than zero, or in math notation: . On the other hand, when the graph of the function is above the x-axis, the value of is positive; therefore, the function is grater than zero, or in math notation: .

We can infer from our graph that our function is bellow the x-axis from minus infinity to minus -1, and form three to infinity. In math notation:

on the interval and on the interval

We can also infer from our graph that our function is above the x-axis from 1 to 3, so:

on the interval

Knowing this we can conclude that the true statements are:

on the interval

on the interval

on the interval

on the interval

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
