A Function is defined as the relation between the input and the output where one input can have only one output
When graphing functions, the x-axis denotes the inputs and the y-axis denotes the output of the function
Looking at the graph, we see that for one input (point on the x-axis) we have only one output (point on the y-axis)
Hence, we can say that this graph represents a function
Multiplying a number by 4/5 and then dividing by 2/5 is the same as multiplying by 2
Complementary angles sum upto 90°
so the complement of 9° = 81°
Answer: 
Step-by-step explanation:
We know that probability for any event = 
Given : Charlotte has 6 cherry candies, 3 grape candies, and 3 lime candies.
I..e Total pieces of candies she has = 6+3+3= 12
Now , If Charlotte randomly pulls one piece of candy out of the bag, what is the probability that it will be cherry is given by :-

Hence, the probability that it will be cherry is
.
Y= f(x) = a+bx
example: f(x) = 3x+2
