5 complex roots; 1, 3, or 5 real roots.
Possible rational roots; +/- 1/2, +/- 1, +/- 2, +/-, 3/2, +/- 3, +/- 4, +/- 6, +/- 12
Answer:
A
Step-by-step explanation:
C is located at (5,3).
If you want to reflect this over the y-axis, you need to have the same distance that (5,3) is to the y-axis on both sides.
If you look at your graph you should see that (5,3) is 5 units a way from the y-axis so when you put it on the other side it should be 5 units a way also.
So the reflection will give you (-5,3)
Its a bit tricky to explain without a diagram bot if we take a point (a, b) on the coordinate plane as the center of the circle and another point (x,y) on the circumference then the distance between (a,b) and (x,y) is the radius of the circle.
Now create a triangle by drawing a line horizontally from (a,b) to the circumference and another line prerpendicular to this line from the point (x,y) to make a right angled triangl.e
Applying the pythagoras theorem to this triangle gives
(x - a)^2 + (y - b)^2 = r^2 which is the standard form of equation of a circle.
