Y is inversely proportional to the square root of x. When y=7, x= 2.25. Write y in terms of x.​

y(x)=10.5/sqrt(x)

Step-by-step explanation:

Since y is inversely proportional to the square root of x, it can be written as y=a/sqrt(x). To compute a, we will use the point given in the question (2.25,7). 7=a/sqrt(2.25), a=10.5. The function is y(x)=10.5/sqrt(x)

y = 1/(x**2) + 6.8025

Step-by-step explanation:

This says that y = 1/(x**2) + b where b is the y intercept.

So using the point given

y = 1/(x**2) + b

7 = 1/(2.25**2) + b

7 = 1/5.0625 + b

7 = 0.1975 + b

b = 6.8025
