Answer:
The range of the function in ascending order is:
Range R = {-2, 0, 2, 4}
Step-by-step explanation:
Given the function
f(x) = 2-2x
We know that the domain of the function is the set of input or arguments for which the function is real and defined.
In other words,
- Domain refers to all the possible sets of input values on the x-axis
As the domain of the function is given such as
Domain D = {-1, 0, 1, 2}
<u>Determining the range </u>
We also know that range is the set of values of the dependent variable for which a function is defined.
In other words,
Range refers to all the possible sets of output values on the y-axis.
As the domain is
Domain D = {-1, 0, 1, 2}
FOR x = 1
substitute x = -1 in the function
f(x) = 2-2x
f(-1) = 2-2(-1) = 2+2=4
so
at x = -1, y = 4
FOR x = 0
substitute x = 0 in the function
f(x) = 2-2x
f(-1) = 2-2(0) = 2-0=2
so
at x = 0, y = 2
FOR x = 1
substitute x = 1 in the function
f(x) = 2-2x
f(-1) = 2-2(1) = 2-2=0
so
at x = 1, y = 0
FOR x = 2
substitute x = 2 in the function
f(x) = 2-2x
f(-1) = 2-2(2) = 2-4=-2
so
at x = 2, y = -2
Thus combining all the output or y values correspond to the given input values, we get the range of the function.
Thus, the range of the function in ascending order is:
Range R = {-2, 0, 2, 4}
Answer:
A.) weak positive correlation
The person above just wanted to steal points.
Step-by-step explanation:
Answer:
<u>domain</u>: all real numbers
<u>range</u>: all real numbers greater than -2
Step-by-step explanation:
The domain is all the possible numbers that x, or the inputs to the function, can be. It looks like this function goes on forever both left and right, so its domain is all real numbers.
The range is all the possible numbers that y, or the outputs to the function, can be. It looks like this function starts growing at a y-value of -2 and then goes on forever, so its range is all real numbers greater than -2.
Hopefully that was helpful! :)
