What is the input if the output is -6?

x=0,8

Step-by-step explanation:

We want to find the values of x when y = -6

There are two different values of x that give y = -6

The first is x=0

When f(0) = -6

The second is x=8

f(8) = -6

0 or 8

Step-by-step explanation:

The output is -6

output = y

input = x

When y = -6, x = 0 or x = 8 (as shown in the graph).

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
