Math Problem Statement

Determine the factored form equation of the quadratic relation shown in the graph, where the x-intercepts are (0, 0) and (6, 0) and the vertex is at (3, 3).

Solution

The graph you uploaded appears to be a quadratic function. To find the factored form of the equation of a quadratic, we need to use the x-intercepts and the vertex.

From the graph:

  • The x-intercepts (roots) are (0,0)(0, 0) and (6,0)(6, 0).
  • The vertex is (3,3)(3, 3), which gives us the peak of the parabola.

The factored form of a quadratic equation is:

y=a(xr1)(xr2)y = a(x - r_1)(x - r_2)

where r1r_1 and r2r_2 are the x-intercepts.

Step 1: Using the x-intercepts

The intercepts are (0,0)(0, 0) and (6,0)(6, 0), so the equation becomes:

y=a(x0)(x6)=ax(x6)y = a(x - 0)(x - 6) = a x (x - 6)

y=ax(x6)y = a x (x - 6)

Step 2: Using the vertex to solve for aa

Substitute the vertex (3,3)(3, 3) into the equation to solve for aa:

3=a(3)(36)3 = a (3)(3 - 6) 3=a(3)(3)3 = a (3)(-3) 3=9a3 = -9a a=13a = -\frac{1}{3}

Step 3: Final equation

Now that we know a=13a = -\frac{1}{3}, the factored form of the quadratic equation is:

y=13x(x6)y = -\frac{1}{3}x(x - 6)

This is the factored form of the quadratic equation based on the graph.

5 Related Questions:

  1. How would the equation change if the vertex was lower or higher on the graph?
  2. How can we convert this factored form to standard form?
  3. What is the significance of the value of aa in the graph's shape?
  4. Can the quadratic equation have other forms besides factored form?
  5. How would we find the vertex if it wasn't provided on the graph?

Tip:

When identifying the factored form of a quadratic equation, always start by locating the x-intercepts, then use the vertex to find the value of aa.
