Te the function.
f(x) = -22 + x + 13
Find f(9)

f(9) = 0

Step-by-step explanation:

f(x) = -22 + x + 13

To  find  f(9) put 9 instead of x to the function like this.

f(x) = -22 + x + 13

f(9) = -22 + 9 + 13

f(9) = -13+13

f(9) = 0

Hope this helps you.

Let me know if you any other question :-)

c.

the first option i believe
