Consider the function represented by the graph. what is the domain of this function

The answer is

Step-by-step explanation:  We are given a graph that represents a function. We are to find the domain of the graphed function.

Domain and Range:  If y=f(x) is a function, then the domain is the set of all first elements of ordered pairs (x-coordinates) and the range is the set of all second elements of ordered pairs (y-coordinates).

In the given graph, 'x' takes the values from 0 to infinity and 'y' takes the values from negative infinity to 9.

Therefore, domain of the function is [0,  ∞) and the range is (-∞, 9).

Thus, the domain is given by the set

its 4 because 2 times 2 is 4, if you double the number two you get four

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
