Find the x and y intercepts of a quadratic

👉 Learn about the parts of a parabola. A parabola is the shape of the graph of a quadratic equation. A regular palabola is the parabola that is facing either up or down while an irregular parabola faces left or right. A quadratic equation is an equation whose highest exponent in the variable(s) is 2.
The parts of a parabola include: the axis of symmetry (the line passing through the vertex of the parabola to which the parabola is symmetric about), the vertex (the point at which the parabola turns), the domain (the set of possible x-values of the parabola, usually all real numbers for regular parabolas), the range (the possible y-values of the parabola which is usually the region above the vertex inclusive or below the vertex inclusive for regular parabolas), the x-intercepts (the points where the parabola cuts the x-axis) and the y-intercepts (the point(s) where the parabola cuts the y axis.

    It turned out that x-int = (2, 0) and the y -int = (0, 4) and the vertex is (2, 0) as well ... Is it a happy face parabola that cuts the y axis at ( 0, 4 ) and the x axis at ( 2 , 0 ) which is its vertex and x axis intersection point at same time and bounces afterwards off ( 2 , 0) to change its direction upwards towards the infinity . Its domain is ( negative infinity , positive infinity ) and its range is ( 0 , positive infinity ) .

    Simple factoring; You want y to be 0 since you're looking for the x intercepts Therefore you have (x+1)(x+1)=0 The one solution that would make this equal to 0 is if x=-1 That means you only have one x intercept, at (-1,0)

    expand it out to be x^2 -10x +25. use a generic rectangle or the FOIL method. it is a perfect square trinomial, so x =-5. or, if you don't know that method, then use the method he shows at the end of the video (the diamond thing) you will find that -5 times -5 equals 25, and -5 plus -5 equals -10, so x = -5
