Problem 1
Domain = {-1, -3, 2, 1}
Range = {5, 0, 2}
The domain is the set of possible inputs and the range is the set of possible outputs. This is a function because each input goes to exactly one output.
========================================
Problem 2
This is a function as well. We do not have any input going to multiple outputs.
Domain = {-2, -3, 5}
Range = {6, 7, 8}
========================================
Problem 3
This is not a function. The input -4 goes to more than one output (outputs 3 and -1 at the same time)
Domain = {-4, -2, 0}
Range = {3, -1, -2, 4}
Answer:
-0.48
Step-by-step explanation:
Step-by-step explanation:
That is because 1/3 is not exactly equal to 0.333333. 0.333333 is a rounded number from the real number which 0.3 and the 3 goes on forever. In the image it show the the answer, in where the 3 goes on forever.
Answer:
x=6 2/3
Step-by-step explanation:
Ratio of DEF:ABC=5/3
8*5/3=13 1/3
x=6 2/3
Answer:
All except from point E's y-coordinate (which is -1.5 (found it through the equation y=-1.5 and trying to see if these coordinates are solutions to the above equation) All the others are integers, which you can find through aligning the point on the axis of the chosen (y or x) coordinate.
Step-by-step explanation:
Point C has -2 x-coordinate since it is on the x=-2 line
Similarly, point D has -2 y coordinate,
point E has 2 x-coordinate and -1,5 y-coordinate
and point F , since it's the two axis' common point has coordinates of (0,0).
Hope I helped! Further explanation can be given on request on your behalf.
