Parabola is the locus of a point that moves in a plane such that its distance from a fixed point in the plane is always equal to its distance from the fixed straight line in the same plane. The fixed point is called the focus of the parabola, and the fixed line is called the directr...
Parabola: Each point on the parabola is equidistant from a point (focus) and a line (directrix). The directrix is perpendicular to the parabola's axis. A horizontal axis parabola can be written as {eq}(y-k)^2=4p(x-h) {/eq}, where (h,k) is th...

When x ≤ 0, f(x) becomes a quadratic function with a parabola that passes through the origin and (-2, 4). Since it only applies for 0 and negative numbers, we will only half of the parabola. When 0 < x < 2, f(x) will a represent a constant which is a horizontal line passin...

Quadratic functiony=f(x)=ax2+bx+c always represent a parabola. If the co-efficient of x2is positive , theparabolawill be concave up and negative , the parabola will be concave down. For manually sketch the quadratic function graph, we will find two points for which y=f(x)=0 that me...
Step 1: Identify clearly the given quadratic function, and simplify if necessary Step 2: After simplifying, identify the function in the form f(x) = ax² + bx + c. Notice that a cannot be zero Step 3: If a > 0, you know the graph will be a parabola that opens upward, whereas...
