If <u>quadratic function </u>
has <u>vertex </u>that is the same as its <u>y-intercept</u>, then
and its equation is 
The graph of this quadratic function is translated graph of the function 
up or down (depends on c).
This means that there could be
- two x-intercepts;
- one x-intercept;
- no x-intercepts.
The axis of symmetry of the graph of the function is x=0 (y-axis).
Answer: correct choice is A
<u>Statement</u> <u>Reason</u>
1. altitude AD bisects ∠BAC 1. Given
2. DB is congruent to DC 2. definition of bisect
3. m∠BDA = 90° 3. definition of altitude
4. m∠CDA = 90° 4. definition of altitude
5. m∠BDA = m∠CDA 5. transitive property
6. AD is congruent to AD 6. reflexive property
7. tri BDA is congruent to tri CDA 7. SAS
8. AB is congruent to AC 8. CPCTC
9. tri ABC is isosceles 9. definition of isosceles

Step-by-step explanation:
Answer:
150 degrees
Step-by-step explanation:
75 -----> 75 out of 360
360-75=285
285-75 will be divided by 2
210 divided by 2 equals 105
105 is the measure of the angle I think (lmk if its wrong)
