Chapter 1: Q. 9 (page 23)

True or False :

The y-coordinate of a point at which the

graph crosses or touches the x-axis is an x-intercept.

Short Answer

Expert verified

The given statement is False .

Step by step solution

01

Given information:

The given statement is:

The y-coordinate of a point at which the

graph crosses or touches the x-axis is an x-intercept.

02

Step 2:

Example:y=x+2

Clearly, from the graph, we get, the y co-ordinate is zero for the x-intercept.

∴ The "x co-ordinate" of a point at which the graph crosses or touches the x-axis is an x-intercept.
