Afunction follows the rule y = -75 - 5x. when the function's output is 25, the equation is 25 = -75 - 5x. what is the function input when the output is 25?

The function input is -20 when the output is 25

Step-by-step explanation:

we have

where

y is the dependent variable or output

x is the independent variable or input

If the output is 25

then

y=25

substitute

Solve for the function input is the same that solve for x

Isolate the variable x

Adds 5x both sides

subtract 25 both sides

Divide by 5 both sides

therefore

The function input is -20 when the output is 25
