On a coordinate plane, an absolute value graph has a vertex at (negative 4, negative 2).

g(x) = |x + 4| – 2

g(x) = |x – 4| – 2

g(x) = |x – 2| – 4

g(x) = |x – 2| + 4

Which times and distances are represented by the function? Select three options.

The starting distance, at 0 hours, is 300 miles.

At 2 hours, the traveler is 725 miles from home.

At 2.5 hours, the traveler is still moving farther from home.

At 3 hours, the distance is constant, at 875 miles.

The total distance from home after 6 hours is 1,062.5 miles.
