Describe the key features of a parabola with the equation x2 = 40y.
the value of p is .

the parabola opens .

the coordinates of the focus are .

the equation for the directrix is

ANSWER

p=10

Opens up

Focus:(0,10)

Directrix: y=-10

EXPLANATION

The given parabola has equation;

We compare this to

This implies that,

Hence,

Since p is positive, and the orientation is on the y-axis, the parabola opens up.

The coordinates of the focus are (0,p).

Hence the focus is (0,10).

The equation of the directrix is y=-p.

Therefore the directrix has equation,

p=10

opens up

focus- (0,10)

y=-10

Step-by-step explanation:

thats the answer^ simple

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept
