Step-by-step explanation:
Area of an equilateral triangle = 
Sub in your value of 16ft
A = 
A = 110.85 
One way is to graph it and do the vertical line test
it is not a function if we can draw a vertical line in the graph that passes through 2 points of the graph
if we graph this function, we see there is no place we can draw a vertical line and hit the line twice
