Answer:
a) (-2,-1) b) (-3,0) & (-1,0)
Step-by-step explanation:
For the first part, the turning point is simply where the graph curves. We can see that that happens on (-2, -1).
For the second part, the roots of the equation are simply when the graph crosses the x-axis. This happens twice, at (-3,0) and (-1,0)
Answer: B
Step-by-step explanation: the similar paper appears to be 2 times larger then Fransicos since 38/19=2, so I did 14 1/3*2 which equals 28 2/3, so the answer is B

u take ur known variables and fill them in, pi will be filled in as 3.14
Example:

Then divide both sides by 3.14, after that it should be (number) =r². since it's squared you have to find to square root of both.
Example:

therefore in this example the radius is 7
