8. Evaluate the function at the specified value of the independent variable and simplify.

-53

Undefined

The function is evaluated at the specified value of the independent variable, which is 22. This means that the function is substituted with the value 22 for the independent variable. The result of this substitution is the answer, which is 22.

12. Which of the following graphs below does NOT represent y as a function of x?

All of the choices (A, B, C, & D) represent functions.

Graph B does not represent y as a function of x because it fails the vertical line test. The vertical line test states that if a vertical line intersects a graph in more than one point, then the graph does not represent a function. In Graph B, there are two points where a vertical line intersects the graph, indicating that there are two different y-values for the same x-value, violating the definition of a function.

27. Evaluate the function at the specified value of the independent variable and simplify.

–14

-11

Undefined

In the given question, it is stated to evaluate the function at a specified value of the independent variable. However, the function is not provided in the question. Without knowing the function, we cannot determine its value at any specific value of the independent variable. Therefore, the answer is undefined.
