Answer:
The graph of the equation is given below.
Step-by-step explanation:
We are given the equation, 
On simplifying, we get,
i.e. 
So, the table is given by,
x
y
-4
i.e.
2
0
i.e.
-1
4
i.e.
-4
Thus, the graph of the equation is given below.
For possible roots I got...
1
1/3
5
5/3
Not really sure about a b c or d.
x = -0.76508126
There are two modes in the calculator: radians and degrees. These two differ since the radians has a base unit of pi while degrees does not base on it. In this case, in degrees, using the calculator and shifting the mode to degrees, the answer is equal to 0.013 in which 3/4 is an angle
Right Regular Pyramid
where the base is a polygon of 3 or more sides
