Let A= {x, y, z} and B= { p, q, r, s}, What is the number of distinct relations from B to A ?

Let f, g : R→R be defined, respectively by f(x) = x + 1, g(x) = 2x – 3. Find f + g, f – g and f(g)

Name the property of equality the statement illustrates.
If ∠P ≅ ∠Q, then ∠Q ≅ ∠P.

Let f = {(1,1), (2,3), (0,–1), (–1, –3)} be a function from Z to Z defined by f(x) = ax + b, for some integers a, b. Determine a, b.

Note: All functions are relations but all relations are not functions.

Sketch a graph modelling a function for the following situation:
A dog is sleeping when he hears the cat “meow” in the next room. He quickly runs to the next room where he slowly walks around looking for the cat. When he doesn’t find the cat, he sits down and goes back to sleep. Sketch a graph of a function of the dog’s speed in terms of time.

When a new laptop became available in a store, the number sold in the first week was high. Sales decreased over the next two weeks and then they remained steady over the next two weeks. The following week, the total number sold by the store increased slightly. Sketch the graph that represents this function over the six weeks.

Jack’s Mother brings him a bowl of carrots as a snack. At first he does not eat any. Then he eats one at a time until half of the carrots are gone. Then he does not eat anymore. Sketch a graph that shows the number of carrots in the bowl over time ?

A baseball team scores the same number pf runs in each of the first four innings. After that the team did not score a run for the rest of the game which lasts 9 innings. Let X represents the innings of the game , and y represents total number of runs. Sketch the graph of the situation above. And How would the graph change if the innings in which the team scores runs changes ?
