there are 7.8 calories in a ounce tomato
The correct answer is the graph in the top right corner because it is a constant function. The bottom left graph is also considered a function but is an absolute function. So both are technically correct.
As shown in the figure below the answer is the last option:

The roots of the polynomial in the denominator are:


So, the inequality can be written as follows:

From this inequality we can study the signs and get the same conclusion just as shows the graph.
First, multiply 1/2 and 2 by 6 to simplify the equation. Then, subtract 12 from both sides of the equation to get x alone. Finally divide both sides of the equation by 3 to get x on it's own. That is your solution. X=-2/3 I attached a picture of my work. Hope this helped!
