2 points. You answer this with the vertical line test. There are two pairs of points with the same x-axis, so they make two vertical lines. For it to be a function, it must pass the vertical line test, so no two points have the same x-axis. I hope this helps :)

The data above can be modeled by the function f(x) = 0.0425x^2 + 0.07381x - 0.49107 . Using this equation, predict the skid dist
nataly862011 [7]

Answer:

<em>f(50) = 109.44943 feet</em>

Step-by-step explanation:

<u>Modeling</u>

The model of a situation where the skid distance f is measured against the car speed x can be expressed as:

f(x) = 0.0425x^2 + 0.07381x - 0.49107

Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:

f(50) = 0.0425*50^2 + 0.07381*50 - 0.49107

f(50) = 106.25 + 3.6905 - 0.49107

f(50) = 109.44943 feet
