A parabola is defined as being a curve in which any point is equidistant from a fixed point called the focus and a fixed straight line called the directrix. Practically, a parabola looks like this: A parabola Every parabola behaves in a similar way. If it is upward opening, it will have...
This is not a function since it is a one-to-many mapping. When will parabola open down? In classic geometry, it opens down when the directrix is above the focus.In analytical (coordinate) geometry, if the equation of the parabola isy = ax^2 + bx + c, it opens down if a < ...

[1] Any point on the parabola is equidistant from a fixed point (the focus) and a fixed straight line (the directrix). In order to graph a parabola, you need to find its vertex as well as several points on either side of the vertex in order to mark the path that the points travel...
Describe the steps to find the equation of a line when given two points of intercept? Where would you plug in the slope and y-intercept for a linear equation with a slope of 2 and a y-intercept of -6? How do I find slope?
The revised integrand is {eq}-2x^3+4x^2 {/eq}, which has the same zeros as the function we solved in step {eq}1 {/eq} to find the values of {eq}x {/eq}, which are {eq}x=0 \textrm{ and } x=2 ...
