Work Step by Step
1) Solve for each expression equal to zero. REMEMBER $x^{2}$-4 cannot have an, or equal to, added since it is in the denominator of a fraction. Anything divided by zero is not possible. 2) -2 and 2 will have open circles since it does not include those values while 4 will have a closed circle to indicate it includes that value. 3) There will be a gap between -2 and 2 because that is where x is less than 2 but is greater than, not less than, -2. 4) Refer to the image
