Question

Select True or False for each statement.

True False


A straight line on a coordinate plane always represents a function. (true? or false?)


The equation y=2x+1 represents a function. (True? Or false?)

Answer 1

Answer: 1 is false

Answer: 2 is true

Answer 2

A straight line on a coordinate plane always represents a function. (true? or false?)

2) The equation y=2x+1 represents a function. (True? Or false?)

Explanation:

The domain of a function must not have an element that has at least two different images in the range.

A straight line on a coordinate plane

does not always represents a function.

A vertical line is also a straight line.

All vertical lines will fail the vertical line test.

This statement is false.

2) The given function has equation:

`y = 2x + 1`

This is a straight line that has a slope of 2 and a y-intercept of 1.

This line is slanted so it represents a function because it passes the vertical line test.

This statement is True
