Answer:
a) Exactly 50
Step-by-step explanation:
The range of a function consists in the resulting y-values that we get once we substitute all the possible x-values of a function.
The function of this problem consists of exactly 50 ordered pairs, this means the function has EXACTLY 50 pairs (x,y) where x is the x-value and y is the resulting y-value for that x.
Therefore, we have EXACTLY 50 y-values and therefore the range of f has exactly 50 elements.
