The y-intercept of f(x) has the same value as the The function f1(x) has a range including all values
greater than or equal to 0; therefore, the
does also.

The y-intercept of f(x) has the same value as the -x-intercept of f inverse-

The function f^1 (x) has a range including all values greater than or equal to 0; therefore, the -domain of f- does also

Step-by-step explanation:

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

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
