For a relation to be function, every x value should have its unique image in co-domain. If x is related to more than one y value, then that relation is not a function
In 1, as you can see, 1 related to -7 as well as 8. Which means 1 has two images viz. -7 and 8. But for a relation to be function, x should have only one image. Thus, it is not a function.
The worst is the 4th one in which -2 has 4 images.
Therefore, only relation B is a function.
Let's simplify ~
Therefore, A is the Correct choice !
Answer:
(-4, -2) is the answer
Step-by-step explanation:
is you move 7 units down from the zoo you will see ur also 2 units from the park and the coordinates would be (-4, -2)
Hope this helps :)
You write it as a ratio eg. SF(large→small)=20:7
Answer:
56 degrees
Step-by-step explanation:
Because DF is a line that makes it 180 degrees we know that the other two angles on that line are are 60 and 64 now we can make an equation:
60 + 64 + x = 180
124 + x = 180
Subtract 124:
x = 56
