Ahiker walks up and down a hill. the hill’s cross section can be modeled by the function y = – 3/4|x – 300| + 400 where x and y are measured in feet and d: [0, 600]. how far does the hiker walk?

Find the vertex by either graphing ( See attached picture) or setting the value in the absolute value bracket to 0:

Vertex is (300,400)

Because it is symmetrical, find the length of one side and double ot for total distance.

Using the distance formula shown on the attached picture.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

1 1/5
