Answer:
[tex] \huge f( - 9) = 1[/tex]
Step-by-step explanation:
[tex]f(x) = \frac{x}{3} + 4 \\ [/tex]
To find f(-9) , substitute the value of x that's - 9 into f(x) , that's for every x in f(x) replace it with - 9
We have
[tex]f( - 9) = - \frac{9}{3} + 4 \\ = - 3 +4[/tex]
We have the final answer as
[tex]f( - 9) = 1[/tex]
Hope this helps you
