3. Verte
x -2,4
2,1

4. • Y = a ( x - h )^2 + k
• H,k = (-2, 4)
• X,y = ( 2,1 )
• 1 = a( 2+2)^2 + 4
• 1 = 16a + 4
• -4 -4
• -3 = 16a
• -_3
• 16

5. Final Equation
• Y = -3/16 ( x +2 )^2 + 4

6. Actual Equation
• Y= ax^2 + bx + c
• A= -.3125
• B= -.625
• C= 4
• Y= -.3125x^2 + -.625 + 4

7. • Y = -.1875x^2 - .75x +4
• Y = -.1875x^2 - .75x + 3.25

8. Similarities
• Both negative
• Both open down
• Very close in numbers
