Write the formula for the function whose
parabola is narrow,
opens downward, has a
y-intercept of (0,-3.14),
and has NO x-intercepts.

Equation of the  parabola    x² = -12.56 y

Step-by-step explanation:

Explanation:-

Given Y- intercept ( 0, -3.14)

Given Focus is ( 0 , -a) = ( 0, -3.14)

So  a = 3.14 center C(0,0)

The graph of the parabola is downwards and the axis of the parabola is Y-axis.

Equation of the standard parabola    x² = -4 a y

                                                              x² = -4 (3.14) y

                                                              x² = -  12.56 y

Conclusion:-

Equation of the  parabola    x² = -12.56 y

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
