Answer:

y = - x² + 4

Explanation:

The equation of a parabola whose vertex is on the y- axis is

y = ax² + c

where a is a multiplier and c is the y- intercept

• If a > 0 then minimum vertex

• If a < 0 then maximum vertex

Here vertex is a max, thus a = - 1 and c = 4

Then equation of parabola is

y = - x² + 4
