Let’s check out your problem:

The plot in the $dI$-plane shows the light intensity, $I$, in watts per square meter, at a depth of $d$ meters below the surface of a lake. Which of the following equations best models the relationship between $I$ and $d$? Choose $1$ answer:$\newline$(Choice A) $I = 950 \times 1.65^d$ $\newline$(Choice B) $I = -950 \times 1.65^d$ $\newline$(Choice C) $I = 1610 \times 1.65^{-d}$ $\newline$(Choice D) $I = -1610 \times 1.65^{-d}$
