Use absolute value to write an expression describing the size of each amount. an elevation of 250 feet.

The absolute value of a number is always positive.

if x > 0 , then = x

if x < 0 , then |-x| = x

Use the absolute value.

To find an expression for: An elevation of 250 feet.

Elevation mean the height of a place above the sea level.

An elevation of 250 feet =  +250

then, using absolute value:

Size of each amount,  

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
