Which one of the following statements is false?
a) a full binary tree has an even number of vertices.
b) a binary tree is an m-ary with m = 2.
c) in an m-ary tree, each internal vertex has at most m children.
d) in a full m-ary tree, each internal vertex has exactly m children.

option (a) is false

Step-by-step explanation:

m-ary of binary tree has m=2 is a correct statement.

and the statement (c) and (d) states about  m-ary tree are also correct.

hence, from the given statement option (b) is false because when we count the roots the number of vertices are odd.

for full m ary internal vertex is exactly m children and for an m-ary has atmost m children.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
