Solution

Let’s analyze the problem from the uploaded image. The given quadratic is written in vertex form:

y=3(2x8)2+5y = 3(2x - 8)^2 + 5

We will go step by step to fill out the required information:


  1. Vertex:
    The vertex form of a quadratic is: y=a(xh)2+ky = a(x-h)^2 + k where (h,k)(h, k) is the vertex.
    Here, 2x82x - 8 can be rewritten as 2(x4)2(x - 4), so h=4h = 4 and k=5k = 5.
    Vertex: (4,5)(4, 5).

  1. Axis of Symmetry (AOS):
    The axis of symmetry (AOS) is the vertical line that passes through the vertex. It has the equation: x=hx = h So, the AOS is: x=4x = 4

  1. Range:
    The quadratic opens upwards because the leading coefficient 3>03 > 0. The minimum value of yy occurs at the vertex, where y=5y = 5.
    Thus, the range is: y5y \geq 5

  1. Vertical Stretch:
    The coefficient a=3a = 3 indicates a vertical stretch by a factor of 33.

  1. Horizontal Compression:
    The term 2x2x indicates a horizontal compression by a factor of the reciprocal of 22, i.e., 12\frac{1}{2}.

  1. Horizontal Shift:
    The term x4x - 4 indicates a horizontal shift to the right by 44 units.

  1. Vertical Shift:
    The +5+5 outside the squared term indicates a vertical shift up by 55 units.

Final Answers:

  1. Vertex: (4,5)(4, 5)
  2. AOS: x=4x = 4
  3. Range: y5y \geq 5
  4. Vertical Stretch: 33
  5. Horizontal Compression: 12\frac{1}{2}
  6. Horizontal Shift: 44 units to the right
  7. Vertical Shift: 55 units up
