Answer:
The given graph shows a function of x.
Step-by-step explanation:
Neither 1 nor 3 is a single-valued relation for some values of x. The graph shown passes the vertical line test, so does represent a function.
The graph is a relation that is a function of x.
___
The attached graph is of the equation of 3. A vertical line will intersect the graph in more than one place, so the relation is NOT a function.
Answer:
or
Step-by-step explanation:
we know that
the formula to calculate the distance between two points in three dimensions is equal to
Let
-----> coordinates of the barrel of her gun
-----> coordinates of the target
substitute the values
The functions are:
and 
.
After 2 weeks, under no risk of spiders, the population of the flies is calculated by the function as
.
Similarly, we calculate s(2)=2(2)+5=4+5=9, which means that the spider consumes 9 flies in 2 weeks.
Thus, out of 32 flies, 9 are eaten by the spider, so there are 32-9=23 flies left.
