Answer:
Domain: All Real numbers
CoDomain : All Real numbers
Range: ; that is: Real numbers larger than or equal to zero
Step-by-step explanation:
Notice that the graphed function can use any Real number x (from - infinity to + infinity) and produce an output. Therefore, the Domain of the function plotted in graph 3 is : All Real numbers.
The set of possible outputs (CoDomain) is also the set of all Real numbers (notice that the y-axis extends form - infinity to + infinity
But the Range (the actual set of the collection of outputs of the function) is just a subset of the CoDomain consisting of the Real numbers larger than or equal to zero (notice that the drawing of the function touches the x axis and lies completely on the upper half of the plane.
Answer:
Since, the coordinates of the given triangle are (0,0), (4,-4) and (-4,-2)
In the dilation by the scale factor k with centered at origin,
Thus, If the dilation occurs by the scale factor of 2 with centered at origin,
New coordinates of the triangles are,
Thus, the coordinates of new triangle are,
(0,0) ( -8, 8) and (-8,-4)
