Is the above relation a function?

Which of the relations is not a function?

We can determine whether a relation is a function by looking at itsgraph.→ No ______ points on the graph can have the same __-coordinate(lie on the same __________________ line).→ If a __________________ line drawn on the graph of any functiontouches two points, then the graph does not representa function. (called the ____________________ line test)❖ The only type of straight line that graph fails the vertical line test is a __________________ line.

The function which is considered as function of values of another function is classified as

Consider the relation R defined by the equation y = , where the domain and codomain are specified as follows: Domain: (-∞, ∞) Codomain: [0, ∞)The above relation is a function.

Consider the following relation:{(1, 3), (2, 4), (3, 6), (4, 8), (5, 10)}The above relation is a function with a domain and codomain specified as follows:Domain: {1, 2, 3, 4, 5} Codomain: {3, 4, 5, 6, 7, 8, 9, 10}.Question 12Select one:TrueFalse
