Answer: 46 The number of degrees should add up to 180. 180 - (42+92) = 46
<h3>Given:</h3>
▪ 
You need to remember that the form of an Absolute Value Function is:
•<em> </em><em>For the vertex:</em>
• <em>For the</em> definition:
If "a" is positive (+) , then the range of the function is:
If "a" is negative (-), the range of the function is:
In this case we can identify that:
(1) Paris ∈ F. True (Paris is the capital of France)
(2) The Statue of Liberty ∈ A. False (a statue is not alive)
(3) The Statue of Liberty ∉ M. False (SoL is a monument)
(4) Abraham Lincoln belongs to none of these sets. True
(5) The Eiffel Tower is in more than one of these sets. True (ET is in F and M)
4. The equation is an exponential function where all y coordinates are above 4 (range is y>4), so for y=4 (answer D) there are no solutions. y=4 is the asymptote.
5. In a formula ax^2 + bx + c the discriminant is b^2-4ac. In this example the discriminant is 9-4*3*6 = -63. The fact that this value is negative reveals that this equation has no (real) solutions, only imaginary.
6. y=2x^2-x-5. Trial and error.
