Answer:
The graphs shown is NOT a function.
Step-by-step explanation:
We can use Vertical Line test to determine whether a given relation in the graph is a function or not. A relation is a function if one input results in only one output. If we draw vertical lines on the graph, and any of these vertical line intersect the graph at 2 or more positions, then it means that for one value of x, there are 2 values of y. Hence, for one input, there are more than one outputs. Therefore, the relation will not be a function.
We can see in the attached graph below that any vertical line intersects the graph at 2 positions. Hence, the given relation is graph is not a function.
Apologies for the rough drawing.
You can apply the same technique for the graph of the relation which is not shown, you'll get your answers to fill in the blanks
Answer:
27
Step-by-step explanation:
FE is tangent to the circle with center D at point E and DE is radius.
DE = x
DF = x + 18
FE = 36
By Pythagoras theorem:
Answer:
3B
Step-by-step explanation:
The greatest common factor is the greatest number that will divide two values. We have two values 3B and 30B. Each has numbers which multiply together to give the number. We need to find the highest value or most in common they share. Each has the factors:
3B: 1,3,B
30B: 1, 3, 5, 6, 10, B
Both have 3 and B has factors. Our GCF is these two factors.
