Change ), You are commenting using your Facebook account. On the other hand, if the value of h is added to x in the equation, it is plotted on the left (negative) x-axis. Since every other parabola is created by applying transformations to the base parabola, the step pattern of any other parabola can be found by multiplying the a value of the equation by the step pattern of the base parabola. For example, if we have the equation: y=(x-2)^2, we would do this: As you can see, the real value of h is 2. SWBAT graph quadratic functions in Vertex Form by identifying the Vertex from the equation, and plotting 2 points on each side of the vertex. f (x) = a (x – h)2 + k (a ≠ 0). If the value of k is -4, then the base parabola is shifted to the point -4 on the y-axis. The standard form of a quadratic function presents the function in the form [latex]f\left(x\right)=a{\left(x-h\right)}^{2}+k[/latex] where [latex]\left(h,\text{ }k\right)[/latex] is the vertex.
