Quadratic Equation: Finding Algebraic Expression for Point (5,-4)

Question

Find the corresponding algebraic representation of the drawing:

(5,-4)(5,-4)(5,-4)

Video Solution

Step-by-Step Solution

To solve this problem, we'll use the vertex form of a parabola equation, y=(xh)2+k y = (x - h)^2 + k , where (h,k)(h, k) is the vertex of the parabola.

Step 1: We have the point (5,4)(5, -4) that indicates the vertex of the parabola.

Step 2: Substitute h=5h = 5 and k=4k = -4 into the vertex form equation.

By substitution, the equation becomes:

y=(x5)24 y = (x - 5)^2 - 4

Therefore, the algebraic representation of the parabola is y=(x5)24\mathbf{y = (x - 5)^2 - 4}.

Answer

y=(x5)24 y=(x-5)^2-4
