Step-by-step explanation: You are not asking a question
F of x = function,
meaning the fuction of X equal -13
x=-13
Whats your question?
Answer:
9
Step-by-step explanation:
We know that f(x) = 13. This means that:
f(x)= 13 = 2x-5
13= 2x-5
Now we all need to do is solve this equation. First add 5 to both sides
13 + 5= 2x
18=2x
Now we divide by 2 on both sides.
18 ÷ 2= x
x= 9
