Determine which is the graph of the given function.

a

Step-by-step explanation:

step 1:

for x is less than -5 the f(x) = -3

step 2:

for x is greater than or equal to -5 and less than or equal to 15, f(x)=x+2 and since x contains the value of 15 the Value of x=15 results in f(x)=x+2 15+2=17.

step 3

for x is greater than 15, f(x)= -x+2.

only exists in the graph a.

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
