Answer: Well, you never actually included any instruction, but, i'm gonna say it is the top right graph.
Explanation:
You can deduce that the bottom two are not as the bottom right is going at a consistent rate which makes it linear, the bottom left would be the case if it was an x-intercept of 4. The top left graph is going into the negative x-axis meaning that as x were decreasing, y would be increasing and it is asking for an entire exponential function so you are left with the top right which is in the positive x and y axis and intercepts the y-axis at 4.
