Is a vertical line a function
topjm [15]

Answer:

No

Step-by-step explanation:

Explanation 1)A vertical line can be represented by the equation x=a, where a can be any number. If you think about it, there is no y in the function, this making it not a function.

Explanation 2) For a line to be a function it has to pass the vertical line test, so you will draw a vertical line through the function and if it touches more than one point then it is not a function. In this case if you draw a vertical line through a vertical line there are an infinite number of places where the lines intercept, so it is not a function.

f(x) = { 0.5,   x < 3
         { 1.0,   3 ≤ x < 6
         { 1.5,   6 ≤ x < 9
         { 2.0,   9 ≤ x < 12

The point (2, 12) represents the wage increase of x < 12
