Answer:
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
