That is true.
The diameter is a line that passes through the center of a circle.
Hey there! :)
Answer:
D : [-4, ∞)
R: [-2, ∞)
Step-by-step explanation:
Notice that one end of the graphed function has a closed circle, and one end is a line. We must use specific brackets accordingly:
[ is used for closed points.
( is used for arrows or open circles.
Therefore:
This graph goes from x = -4 towards x ⇒∞. Therefore:
D : [-4, ∞)
The range of this function goes from x = -2 towards y⇒ ∞. Therefore:
R: [-2, ∞)
If

, then by the remainder theorem

has a remainder of 0, which means

is divisible by

. In fact,

So we know 1 is a root, and the other two roots are -1 and -3.
Fraction division is basically multiplication of a reciprocal.
For example (1/4)/(1/8) = (1/4)x(8/1)=2
Multiplication of the answer and the piece that divides (in this case 2 x 1/8), you should get the piece that is being divided (in this case 1/4). If that is correct, then your division is correct.
