Question

1.) What is true about functions?

(a) a set of points (x,y) such that every x-value has
one y-value (for every input there is one output).
(b) passes the vertical line test on a graph
(c) can be represented as an equation in terms of x
and y.
(d) all of the above

Answer 1

Answer: D

Explanation:

If every X value has only 1 Y value then it will pass the vertical line test so that checks out both a and b

c- we can represent all functions in terms of x and y

Answer 2

D

Explanation:

(d) all of the above. All of the statements listed are true about functions. A function is a set of points (x,y) such that every x-value has one y-value (for every input there is one output). This means that for each value of x, there is only one corresponding value of y. Functions can also be represented as an equation in terms of x and y, and when graphed, they pass the vertical line test, which means that if a vertical line is drawn on the graph and it intersects the graph in more than one point, the graph is not a function.
