Answer:
which agrees with answer B
Step-by-step explanation:
First write the equation that represents this type of variation:
then we need to solve for "x" when y = 10 as shown below:

Answer:
-3
Step-by-step explanation:
we khow that the vertex form of a function is written this way :
f(x)=a(x-h)²+k
- the coordinates of the vertex are (h,k) so from the graph we can deduce that k = -3
Answer:
π (or 270°)
Step-by-step explanation:
I use the trick with the coordinates.
(0, -1)
cos270° = 0 (the x-coordinate)
sin270° = -1 (the y-coordinate)
This trick works depending on the radius.
