Answer:
The height of ball when it is at maximum height is 12 unit
Step-by-step explanation:
Given as :
A ball is thrown by child to height y
And y as a function x is y = 
So, for maximum value of height ,
= 0
Or ,
= 0
Or,
= 0
Or,
= 2
or, x = 12
Hence The height of ball when it is at maximum height is 12 unit Answer
You can make a proportion. -12/y=9/4 -12*4-9=5.33

Step-by-step explanation:
Your first step is to solve for y on both equations.
You solve treat the inequality sign just like an equal sign and solve for it.
Graph your equations as if the inequality sign isn't there.
Use dotted lines for < and >
Use solid lines for ≤ and ≥
If it's less than, < or ≤, then shade underneath the line.
If it's greater than, > or ≥, then shade above the line.
