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:
114
Step-by-step explanation:
5.70 TIMES 20 = 114.
Answer:Place the spike of the compass on point Q and draw an arc somewhere below the arm MN. Place the spike of the compass on point P and draw another arc which cuts the arc drawn in the previous step at some point (say R). Connect the points P and R and the points Q and R using a straightedge. The figure PMQR is a square.
Answer:
DB = 13 cm
Step-by-step explanation:
ΔCAB ≅ ΔDBA by ASA, so CA ≅ DB by CPCTC.
CA = 13 cm, so DB = 13 cm.
