Answer:
Yes
Step-by-step explanation:
Graphs are functions when there is only one output for every input. In other words, for every "x" value, there must be only "y" value. This graph depicts a function because it abides by this rule. To be exact, this is an exponential function with the formula: f(x) = (x + 2)².
Since the legs of the triangle are 1 and 1 the hypotenuse would be 1 also. And since squares have equal sides you know that every other side of the square are 1. The algorithm for area is base times height. So 1 times 1 is 1 unit squared.<span />
