y = x2 + 3
Since the x term is missing, the x-coordinate of the vertex is 0.
If x = 0, then y = 3.
Thus, (0, 3) is the vertex, the minimum point of the parabola.
what you have here is the equation for a "porabola" which is pretty much an arch which can be graphed on a number plane with an x and y axis. in this case the porabola cuts the x axis at 4,5 the y axis at 20 and has a vertex of (4.5,-0.25)
no
x2+y2=2y into polar coordinates When converting Cartesian coordinates to polar coordinates, three standard converstion factors must be memorized: r2=x2+y2 r*cos(theta)=x r*sin(theta)=y From these conversions, you can easily get the above Cartesian equation into polar coordinates: r2=2rsin(theta), which reduces down (by dividing out 1 r on both sides) to: r=2sin(theta)
the name is squared equation
No, It's a a quadratic equation because you have X squared.

A quadratic equation.

Sin squared, cos squared...you removed the x in the equation.
No, It's a a quadratic equation because you have X squared.
square root(x2-x1)squared+(y2-y1)squared

A squared plus b squared equils c squared
The 64 is equal to the radius squared. Therefore, 8 is the radius and the 9 and 3 are the coordinates of the center. Area of a circle is Pi * radius squared. In this case that is 64 times pi. or approximately 201.062
