This can be determined by subbing y=0 and solving the equation. The x-intercepts of zeroes is where the lines of a parabola crosses the x-intercept. y=0.Įxample y=2(x-4)^2+8 this equation will then change intoĠ=2(x-4)^2+8 (sub "0" in for the variable "y" ) To figure out what the "x" intercept is, you would have to subsitute "y" into zero. if The value of "a" is negitive then it would go down. The syntax of the equation involves the vertex, the maximum or minimum point of. Or even you could think of just by your knowledge if the "a" value is positve then it would open up. The vertex form is one of the two main ways to represent a quadratic equation. The resultant equation is the standard form. 1.1.2 Step 2: Simplify the other numbers. 1.1 From vertex to standard form conversion: 1.1.1 Step 1: Simplify the binomial by multiplying by itself. you could tell if it opens down or up by A positive "a" draws a smiley, and a negative "a" draws a frowny. 1 Quadratic equation of parabola: Vertex to Standard form. I t also represents whether the quadratic opens up or opens down.

The "a" in this equation indicates the stretch/compression (The strtch or compression will multiply the verticle part of the step pattern.

The swtich of the signs DO NOT occur to figuring out the "K" value. In the case of figuring out where 'K" goes, you would just have to know that if the value is negative it stay negative and if the number is positive the number will be positve. The "K" in this equation represents the vertical transaltion, so how far up or down the graph is shifted from x=0 Or the orgin. Therefore a switch occurs for the signs.Įxample: if the equation is y = 2(x - 4)^2 + 8, the value of h is 4, and k is 8. The vertex form is a special form of a quadratic function. When written in vertex form h k is the vertex of the parabola and x h is the axis of symmetry. On the other hand the intercept form of a quadratic equation is. This quadratic equation is in the form y ax2 bx c. If "H" is a negative number, therefore the number will be transformed into positive. The process for graphing each is slightly different. if the Value of 'H" is Positive then the number would be negative. meaning how far left or how far right the graph is shifted from x=0 also known as the orgin.

The "H" in this quadratic equation represents a Horizontal translation. Both the "K" and "H" represent the vertx of the porabala
