The table represents the function f(x). when f(x) = –3, what is x?

Step-by-step explanation:

we know that

Observing the table

For

The value of the function f(x) is equal to

therefore

That means----> The value of the function f(x) for

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
