Demetrius is drafting a parabola on a coordinate plane. He plans to have the focus at (3,1) and the directrix at y=−3 . What is the equation in standard form that represents the parabola?(1 point)

Question

Responses

y=18x2−54x+178
y equals Start Fraction 1 over 8 End Fraction x squared minus Start Fraction 5 over 4 End Fraction x plus Start Fraction 17 over 8 End Fraction

y=−18x2−2x+1
y equals negative Start Fraction 1 over 8 End Fraction x squared minus 2 x plus 1

y=18x2−34x+18
y equals Start Fraction 1 over 8 End Fraction x squared minus Start Fraction 3 over 4 End Fraction x plus Start Fraction 1 over 8 End Fraction

y=−18x2−54x+38

Answer 1

y=18x^2-54x+178
