Question

write the equation as given by the statment. Then write the indicated function using functional notation.

a helicopter is at an altitude of 1000m and is x m horizontally from a fire. Its distance d from the fire is the square root of the sum of 1000 squared and x squared.

Answer 1

@ganeshie8 what to do?

Answer 2

They basically tell you everything, all you need to do is interpret this:
distance d from the fire is the square root of the sum of 1000 squared and x squared.

into this (use d(x) since distance d is a function of x):
\[\Large d(x) = \sqrt{x^2+1000^2}\]
