Find the value of z such that 0.9722 of the area lies between -z and z. round your answer to two decimal places.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
