Math Problem Statement

Write an equation for the function graphed above.

Solution

The graph you've uploaded shows multiple parabolic functions, each with different transformations. Let’s analyze the features of the graph to write an equation.

  1. First Parabola (on the left):

    • This parabola opens upwards and appears to be vertically shifted upwards by about 6 units.
    • The vertex is located at (3,6)(-3, 6).

    The general equation for a parabola is y=a(xh)2+ky = a(x - h)^2 + k, where (h,k)(h, k) is the vertex. For this graph: y=a(x+3)2+6y = a(x + 3)^2 + 6

  2. Second Parabola (in the middle):

    • This parabola opens upwards and seems to be shifted horizontally to the right by about 2 units and vertically shifted down by 2 units.
    • The vertex is at (1,2)(1, -2).

    Using the same formula, the equation is: y=a(x1)22y = a(x - 1)^2 - 2

  3. Third Parabola (on the right):

    • This parabola also opens upwards and is horizontally shifted right by 4 units, vertically shifted down by 4 units.
    • The vertex is at (4,4)(4, -4).

    Therefore, the equation for this graph is: y=a(x4)24y = a(x - 4)^2 - 4

Each of these equations is of the form y=a(xh)2+ky = a(x - h)^2 + k, where the constants aa, hh, and kk adjust the position and shape of the parabola.

Would you like to know more details about how these transformations work, or have any specific questions? Here are 5 related questions you could explore:

  1. How do the coefficients aa, hh, and kk affect the graph of a parabola?
  2. What happens when the value of aa is negative in a parabolic equation?
  3. How do you find the vertex of a parabola from its equation?
  4. How does horizontal shifting work in the equation of a parabola?
  5. Can you describe the process for determining the transformation of a quadratic function from its graph?

Tip: The value of aa determines how "wide" or "narrow" the parabola is. A larger absolute value of aa makes the parabola narrower, while a smaller absolute value makes it wider.
