Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation. If y varies inversely as the square of x, and y=7/4 when x=1, find y when x=3

y=7/36

Step-by-step explanation:

Since y varies inversely to the square of x, we can say

where z is the constant of variation.

Then, from knowing that y=7/4 when x=1, we plug them in to find z.

Now we have the full equation,

Plug x=3 in and we get,

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
