In 16 cranks, the box is lifted 6 feet. This is basic graph reading. We’re told x is the amount of cracks and y is height in feet. So at point F, we are at 16 cranks (x) and the corresponding feet (y) is 6 feet

Answer:

You can determine the root of the equation by multiple methods. However, that answer is correct. The root is -2.

Step-by-step explanation:

A root is where the graph crosses the x-axis. One trick I use to see if it is a root is by taking the numerator and plugging in the number for x. For example, $\frac{x+2}{x^{2} -2}$ , and take the -2 and plug it in for x. The numerator would cancel out because -2 + 2 = 0. That is the way you can determine if it is a root or not.
