A 2 year old could answer this.

  B.  x = 3

Step-by-step explanation:

The graph is shown below. The solution is the x-coordinate of the point where the graphs cross. That point is (3, -3), so the solution is x = 3.

Comment on the question

A 2-year old might have difficulty with the idea of an exponential function, but certainly a 4-year old can operate a graphing calculator well enough to answer this.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
