Standard Form of an Equation of a Circle is  

Standard Form of an Equation of an Ellipse is  

Standard Form of an Equation of an Hyperbola opening up and down is: 

Standard Form of an Equation of an Hyperbola opening right and  left is: 

the vertex form of a Parabola opening up(a>0) or down(a<0), 

 the vertex form of a Parabola opening right(a>0) or left(a<0), 

where(h,k) is the vertex and  y = k  is the Line of Symmetry



x = (y-4)^2 -2  Parabola Opening right along y = 4, V(-2,4)

y = 4 ± sqrt(x+2), Domain x > -2

c: not a function, will not satisfy the vertical line test. Note x = 5 (Blue vertical line)

(2 values of y for one x-value )

 Parabola in standard form, and graph has horizontal symmetry axis.   Vertex (-2,4).  Parabola opens to the right.  This is a relation, not a function.  The graph is two functions put together.  You see in the graph each point of the graph shares the same x value as one other point,except the vertex.  Each y value has two x values, so the graph is not a function.  No points occur to the left of .





Domain is Real numbers greater than -2.

Range is all Real numbers.
