Question 3 multiple choice worth 4 points)
(04.01)
the graph of a function is shown:
3-
20
which of the following correctly identifies the set of outputs?
{(5,-2). (1.-1). (-2, 2). (2.5);
of(-2.5). (-1, .–2). (5.2);
0 -2.-1.2,5
{-2. 1. 2.5

1. You must apply the Secant and Tangent segment theorem, which establishes:

 Tangent²=(The whole secant segment)(External secant segment)

 2. The whole secant segment is: AD=a+12

 3. The external secant segment is: BD=10

 4. The tangent segment is: DE=12

 5. Then, you have:

 DE²=ADxBD
 12²=(a+10)10
 10(a+10)=12²

 6. Therefore, the answer is the third option: 10(a+10)=12²
