Pre-Calculus Final Exam - Semester 1 Review A

The slope and y-intercept form of the equation of a line that has the given slope m = 6 and passes through the given point (0, -8).

• y = 6x - 8

• y = 8x - 6

• y = -6x + 8

• y = 6x + 8

Determine whether the relation represents y as a function of x.

• No, the table does not represent a function. the input values are each matched with two output values.

• No, the table does not represent a function. the input values of 0 and 1 are each matched with two different output values.

• Yes, the table does represent a function. Each input value is matched with only one output value.

• No, the table does not represent a function. The domain value of 2 is only matched with one output value.

Find the domain of the function.

 $g\left(x\right)\ =\ \frac{1}{x}-\frac{7}{x+6}$  

• all real numbers except   $x\ge-6\ and\ x\ \le\ 0$  

• all real numbers except x = -6 and x = 0

• all real numbers such that  $x\ge-6\ and\ x\le0$  

• all real numbers

• only x = -6 and x = 0

use the vertical line test to determine whether the graph represents y as a function of x.

• yes, y is a function of x.

• No, y is not a function of x.
