Which values are with in the range of the piecewise defined function?

Answer:
y = -6; -3; 0
Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.
Please see the attached image below, to find more information about the graph
The equation is:
f(x) = 2x+2 , x < -3
f(x) = x, x = -3
f(x) = - x -2 , x > -3
From the graph, we can see that the values are
y = -6; -3; 0
The range of the piecewise defined function is:
y= -6 , y= -4 , y= -3 , y=0
The piecewise function is defined by:
f(x) = 2x+2 when x < -3
x when x = -3
and -x-2 when x > -3
Then the graph of the function is a strictly increasing function and is a line with a slope of 2.
The function increases continuously from -∞ to -4
i.e. it takes all the value in the interval (-∞,-4)
There is a open circle at (-3,-4)
The graph of the function f(x) is strictly decreasing .
Since the graph is a line with slope -1.
Also, there is a open circle at (-3,1)
and the function starts decreasing continuously and will take all the values strictly less than 1.
i.e. the range for x > -3 is: (-∞,1)
The range of the whole function f(x) is:
(-∞,1)
