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:
p= -1
Step-by-step explanation:
gradient=<u>y</u><u>²</u><u>-</u><u>y</u><u>¹</u>
<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>x²-x¹
-1 =<u>p</u><u>-</u><u>2</u>
<u> </u><u> </u><u> </u><u> </u><u> </u>9-6
-1=<u>p</u><u>-</u><u>2</u>
<u> </u><u> </u><u> </u><u> </u><u> </u> 3
multiply both sides by 3 to remove the denominators
-1×3=p-2
-3=p-2
put the like terms together
-3+2=p
-1=p
The question isn’t clear, can you write it better so I can understand?
The second one because 5.40 is less than 5.71
