Two different functions are shown.

function a:

function b:

how do the x-intercepts of the two functions compare?

the x-intercept in function b is one-third as large as the x-intercept in function a.
the x-intercept in function b is three times as large as the x-intercept in function a.
the distance between the x-intercepts in function a is half the distance between the x-intercepts of function b.
the distance between the x-intercepts in function a is twice the distance between the x-intercepts of function b.

Let us imagine that the number of automobile accidents in a certain region are related to the regional number of registered automobiles in tens of thousands (b1), alcoholic beverage sales in $10,000 (b2), and decrease in the price of gasoline in cents (b3). furthermore, imagine that the regression formula has been calculated as: y = a + b1x1 + b2x2 + b3x3 where y = the number of automobile accidents, a = 7.5, b1 = 3.5, b2 = 4.5, and b3 = 2.5 calculate the expected number of automobile accidents for a football weekend if the region has 25,000 registered vehicles, $75,000 worth of beer is sold, and a gas war causes a 10 cent drop in a gallon of gas.

Michael gose to a theme park and rides two different roller coasters that both begin on a raised platform his height while on the first roller coaster measured in feet from the platform height can be modeled by the following graph where t is the number of seconds since the ride began
