Answer:
The last equation matches the graph
Step-by-step explanation:
The reason why this graphing correspond to y=-2^x is because we know the parent function of f(x)=2^x is going to be the reflection over the x-axis with respect to this graphing giving , in another word if we were to multiply -1 to 2^x then the function is going to go from monotonically increasing at interval x=(-infinite, infinite), to monotonically decreasing at x=(-infinite, infinite), which is going to look exactly the same as the giving graph
