To solve this question, we use the factor theorem, and using it, the polynomial function is:

------------------------------
The factor theorem means that if k is a root of f(x), f(k) = 0.
Thus, applying the factor theorem for this question, we have to choose the function for which: 
------------------------------
Function 1:

Testing the values:



Thus, since all three conditions are satisfied,
is the polynomial function.

First combine like terms ,
5/5x=9/5x
move the variable which will cancel out because it is the same
5=9 is no solution sorry if i’m wrong lol
Answer: Well theres no table added but it probably looks like this
X Y
8mph 4 min
2mph 1 min
I think you can do the rest
Answer:
3x+4
Step-by-step explanation:
f(g(x))=3(x+2)-2
=3x+6-2
=3x+4
