Answer:
y = ± [ √(x+4) ] / 3
Step-by-step explanation:
1) To find the inverse of the function y = 9x2 – 4, exchange the variables x and y, and then solve for the new y.
2) Exchange of the variables: y = 9x^2 – 4 → x = 9y^2 – 4
3) Solve for y:
=> 9y^2 = x + 4
=> y^2=> y = ± [ √(x + 4) ] / 9
= > y = ± [ √(x + 4) ] / 3
cuase (most likely):
water pressure
Step-by-step explanation:
a house spicket or water source of other types where it comes from a pipeline or pump, the water gets pushed through the pipe/hose into the sprinkler mechanism, forcing it through the channel of holes and shooting the water into the air
NOTE this does NOT apply for all sprinklers, but the common model works this way
