Answer:
Option C
Explanation:
Let's look at the graphs one by one:
The graph has rising and falling exponential functions, therefore, it will not fit the pattern. The graph has a negative exponent function.
Let's skip graph C.
Graph B looks like the correct answer, however, the graph has a negative exponent and then rises up again.
Graph D is out of question as it has uneven exponents.
Graph C has an even function.
