Choose the end behavior of the graph of each polynomial function. (here are the options for all 3 questions)
a. falls to the left and rises to the right
b. rises to the left and falls to the right
c. falls to the left and falls to the right
d. rises to the left and rises to the right
question 1. f(x) = - 4x^6 + 4x^3-8x + 5
question 2. f(x) = -5x ^3 + 7x^2 + 8x -6
question 3. s(x) = 3x (x + 1)(x - 4)^2

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.
