Chapter 1: Q. 80 (page 25)

If the graph of an equation is symmetric with respect to the x-axis and 2is a y-intercept, name another y-intercept.

Short Answer

Expert verified

The other y-intercept is -2.

Step by step solution

01

Given information

The graph of the given equation is symmetric to the x-axis and y-intercept is 2 .

02

Determine the other y-intercept.

As the y-intercept is 2therefore the point (0,2)is on the axis.

When the graph of an equation is symmetric with respect to the x-axis, then if point (x,y)is on the graph, so is the point (x,-y).

Therefore, the point (0,-2)is also on the graph of the equation.

03

Write the conclusion

They-intercept is-2.
