question 1 of 3 What part is shaded for the graph of y < x^2 - 1? The area outside of the parabola The area inside the parabola Just the parabola itself The areas outside and inside of the parabola but not the parabola itself ...
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...
Also, graph the parabola. y² + x + y = 0 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 ...
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...

the parabola passes through this two points and the concavity of parabola depend on the co-efficient of x2. As for example y=f(x)=x2-5x+4=(x-1)(x-4). If x=1 or x=4, then y will be zero.That means the parabola passes through (1, 0) and (4, 0). Since the co-...
Domain. The domain of y = sec (x) is all real numbers x, except x = ± [(2n +1)π] / 2. In other words, the domain of the secant function excludes π/2 +kn, where k is applicable for all integers. Ordered pairs of the form (x, sec (x)) make up the secant function. ...
