Answer:
The required function which represent the Mark's height above sea level over time is [tex]y=1.5x+1[/tex]
Step-by-step explanation:
Given : Mark starts a rock climb when he is 1 mile above sea level. He can climb at the rate of 1.5 miles per hour.
To find : Functions would express Mark's height above sea level over time?
Solution :
Let x be the time in hours and y is the height of Mark's.
The the linear function form,
[tex]y=mx+b[/tex]
Where, b is the initial value or distance he cover,
b=1 mile
m is the slope or rate at which he climb,
m=1.5 miles per hour.
Then the linear function is [tex]y=1.5x+1[/tex]
Therefore, The required function which represent the Mark's height above sea level over time is [tex]y=1.5x+1[/tex]
