Answer:
x=y^2-2
Step-by-step explanation:
This graph, is a parabola that opens to the right.
To answer this question, we just use the vertex form of a sideways parabola- x=a(y-k)^2+h.
In this case, the vertex is (-2, 0), and our value of a is 1, since it opens to the right.
This gives us: x=1(y-0)^2+(-2)
Which simplifies to: x=y^2-2.
Also, the answer to the previous two questions are wrong.
The D value (Domain) is actually [2, ∞)
The R value (Range) is actually "All real numbers" (-∞, ∞)
Let me know if this helps!
Vertical angles, because the definition of vertical lines is each of the pairs of opposite angles made by two intersecting lines.
Answer:
The slope is 
.
Step-by-step explanation:
The equation is conveniently in slope-intercept form.
m - slope
b - y-intercept
-2/3 is in m's spot, so it is the slope of the equation.
Hope this helps.
Answer:
3
Step-by-step explanation:
The radius is half of the diameter so 6/2 is 3
