Step-by-step explanation:
The graph of an exponential function shows a geometric increase or decrease using a curve
<h3>Exponential graphs</h3>
Exponential functions are inverse of logarithmic functions. The standard exponential function is expressed as:
y = ab^x
where
a is the base
x is the exponent
The graph of an exponential function shows a geometric increase or decrease using a curve. According to the function given there will a decrease rate due to the value of the rate value given which is less than 1. The graph of the function given is attached below;

First, draw a diagram. The datum level would be where the helicopter is at up in the sky. An angle of depressing means that instead of rising, the angle start from the horizontal and moves clockwise. Then, you have the altitude which forms a vertical line opposite to the 18 degrees. You are to find x which is adjacent to the 18 degrees. Since the diagram forms a right angle, you use the tangent function:
tangent 18 = opposite / adjacent
tangent 18 = 1560 / adjacent
adjacent = 4,801.19
Thus, the horizontal distance is 4,801.19 ft
