The expression 2x + 50 represents the elevation above sea level, in meters, of a rock climber after x minutes of climbing.
Archy [21]
<span>The expression 2x + 50 represents the elevation above sea level of the climber. It can be written as a function as follows:

f(x) = 2x + 50 where f(x) is the height and x is time.

We can obtain the initial height when we set time 0 in which the climber has not started climbing yet. Therefore, the initial height of the climber would be 50 meters above sea level.</span>
