Fountain Design Option 2• Pick x-intercepts to be 0 and 98 (d = 98)
• Vertex is at (49,61) where I picked height of 61 feet.
• Y = a(x – p)(x – q)
Fountain Design Option 2• Pick x-intercepts to be 0 and 98 (d = 98)
• Vertex is at (49,61) where I picked height of 61 feet.
• Y = a(x – p)(x – q)
• 61 = a(49 – 0)(49 – 98)
Fountain Design Option 2• Pick x-intercepts to be 0 and 98 (d = 98)
• Vertex is at (49,61) where I picked height of 61 feet.
• Y = a(x – p)(x – q)
• 61 = a(49 – 0)(49 – 98)
• 61 = a(49)(-49)
Fountain Design Option 2• Pick x-intercepts to be 0 and 98 (d = 98)
• Vertex is at (49,61) where I picked height of 61 feet.
• Y = a(x – p)(x – q)
• 61 = a(49 – 0)(49 – 98)
• 61 = a(49)(-49)
• 61 = a(-2401)
Fountain Design Option 2• Pick x-intercepts to be 0 and 98 (d = 98)
• Vertex is at (49,61) where I picked height of 61 feet.
• Y = a(x – p)(x – q)
• 61 = a(49 – 0)(49 – 98)
• 61 = a(49)(-49)

Again, sketch your arc on graph paper by plotting the x-intercepts and the vertex. Then, sketch an arc between them!
