Go to the left-most point on the graph. That point is (-3,-2). The x coordinate of this point is x = -3.

So the smallest x can be is x = -3. The variable x can't be any smaller. It can be larger than -3.

Since x can equal -3 or be larger, this makes the domain to be x \ge -3 (x is greater than or equal to -3)

In interval notation, you would write [-3, \infty)
The square bracket tells you to include the endpoint -3 while the curved parenthesis tells you to exclude infinity as an endpoint. Plus or minus infinity is always associated with a curved parenthesis.

In short, the answer is choice D

Please help what does B and C equal
lapo4ka [179]

Answer:

m∠b=20°

m∠c=160°

Step-by-step explanation:

∠c and the 160° angle are vertical, so they are congruent.

m∠c=160°

∠c and ∠b are supplementary, so their sum is 180°.

b+160=180

b=20

So, m∠b=20°.
