Identify the number as real, complex, pure imaginary, or nonreal complex. (more than one of these descriptions may apply.) negative 1 a)non real complex b)real c) pure imaginary d)complex

Since the number sets follow this pattern of inclusions:

and , we can deduce that -1 is also a real number and a complex number (since if an element belongs to a set, it also belongs to all the supersets of its set).

So, the correct options are B and D.

c

step-by-step explanation:

because of the levels

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
