The altitude above sea level of an airplane just after taking off from an airport on a high pleteau is given by the linear function h(t) = 1000t + 3856, where h(t) is in feet and t is the time in minutes since take off. FInd the altitude of the airplane after 2 minutes.
Some one please explain this to me. I have been working on this problem for an hour.

The airplane is taking off from a plateau 3856[ft] in elevation, and is climbing at a rate of 1000[ft] per minute.
(Rate of climb X # of minutes) + elevation from which airplane took off

Since h(t) is the height, we can set t=2 for the time in 2 minutes since take-off. So the answer is h(2). Putting this in your equation:
h(2) = 1000(2) + 3856 = 5856. By the way, your height equation is impossible since the airplane can never come down.

just sustitue in the values t = time = 2 minutes
h(t) = 1000(2) + 3856 = 5856

the answer would be 5856 you just insert the 2 minutes for the variable t, h (t) = 1000 (2)+3856 so h(t)=5856

Just substitute t = 2
