Mom signs up for a new cell phone plan for $110. The Plan includes 4GB data time each month without additional charge. If more data is needed, it will cost $10 for each additional

1. Write an equation for "C" (total monthy cost of the plan) including the additional cost
of any GB used beyond 4 GB.
C =
+/- (pick one)
X

(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.

cause it equals more
