Which statement holds true for absolute value functions?
a) the absolute value determines the direction in which the graph opens.
b) the coefficient determines the line along which the graph is symmetrical.
c) the distance between the left and the right arm is based on the coordinates of the vertex.
d) the vertex coordinates and the absolute value determine the region of the graph on the plane.

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
