Which statements about the graph of the function f(x) = -x2 - 4x + 2 are true? select three options.
the domain is {x|x 5-2.
the range is {yly s 6).
the function is increasing over the interval (-0. -2).
the function is decreasing over the interval (-4, 0).
o the function has a positive y-intercept.

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

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.
