If D is true, why is the quadratic called the Quadratic Parent <em><u>Function</u></em>?
So D is wrong.
A quadratic traces a parabola, so C is wrong.
If it was in Quads 3 and 4 then the formula would be y = - x^2. That's not a parent function. It is one that is derived from the parent. A is wrong
B is the right answer. The vertex is on the origin.
Answer:
1. P= 80
60/.75=80
2. x= 5/3
-27/25x / -27/25= -9/5 / -27/25
-9/5 / -27/25 --- -9/5 x -25/27
3. -300
-2.7/-2.7 = 810/-2.7
4. 120
84x100/70
<u>84/x = 70/100</u>
Answer: the answer is overt and structured
