Nine times the input minus seven is equal to the output. which of the following equations describe this function? a.9y-7=x b.7y-9=x c.9x-7=y d.7x-9=y

Consider the function y = f (x), the element 'x' is the input of the function, and 'y' is the value of the function or the output.

Now, we have to determine the equation for " Nine times the input minus seven is equal to the output"

Since, the input of the function refers to the variable 'x' and output of the function refers to the variable 'y'.

The required equation is:

So,

Therefore, 9x-7=y is the required equation.

Therefore, Option C is the correct answer.

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.
