Answer:
669
Step-by-step explanation:
12+73*9=669

The degree of f(x) is 4. Also the leading coefficient is 1 and it is positive
So as x approaches infinity then y approaches infinity
as x approaches -infinity then y approaches infinity
The first and fourth graph goes up and it satisfies the above . so we ignore the second and third graph.
Now we check the x intercepts of the first graph
x intercepts of first graph is -4 and 2
Plug in -4 for x in f(x) and check whether we get 0


Now plug in 2 for x and check

So -4 and 2 are the x intercepts that satisfies f(x)
Hence first option is the graph of 
Answer:
The dots shown on the graph have a rise of 6 and a run of 4 (so 6/4)
This fraction can be reduced so your answer is 3/2
Idk sorry I would answer if I did but I need points to ask a question
