Answer:
Step-by-step explanation:
Let w be weight of emu egg in pounds.
We have been given that an ostrich egg weighs 2.9 pounds.The difference between the weight of this egg and the weight of an emu egg is 1.6 pounds.
We can represent this information as:
Therefore, the equation will give us the weight of the emu egg, w, in pounds.
Answer:
A - Not Function
B - Function
C - Function
D - Not Function
E - Function
Step-by-step explanation:
For a relation to be a function, each value of input should have exactly one output. Which means that for one value of x, there should only one value of y. If the relation has repetition of x in its ordered pairs, it means that for one value of x, there are two or more values of y, hence the relation is not a function
(Consult the diagram below)
<h3>A - {(6,12),(3,1),(−1,13),(6,4)} </h3>As x = 6 is being repeat, it means that x=6 has two values of y that are 12 and 4. IT IS NOT A FUNCTION.
<h3>B - {(−1,−2),(−4,−4),(0,−5),(7,−5)} </h3>No repetition of x, IT IS A FUNCTION.
<h3 /><h3>C - {(−5,1),(4,10),(5,10),(6,7)} </h3>No repetition of x, IT IS A FUNCTION.
<h3 /><h3>D - {(−1,4),(1,6),(−1,−2),(0,7)} </h3>As x = -1 is being repeat, it means that x=-1 has two values of y that are 4 and -2. IT IS NOT A FUNCTION.
<h3>E - {(−2,8),(2,1),(−4,8),(7,9)}</h3>No repetition of x, IT IS A FUNCTION.
