The graph of the function f(x) = –(x + 6)(x + 2) is shown below.

On a coordinate plane, a parabola opens down. It goes through (negative 6, 0), has a vertex at (negative 4, 4), and goes through (negative 2, 0).

Which statement about the function is true?

A. The function is increasing for all real values of x where
x < –4.

B. The function is increasing for all real values of x where
–6 < x < –2.

C. The function is decreasing for all real values of x where
x < –6 and where x > –2.

D. The function is decreasing for all real values of x where
x < –4.

I'm quite sure that it's A, but just wanted to double-check.

2 2/3 hours duhh silly

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.

the answer is

d.

5.3066 m2
