To find: the coordinates of three additional points on the graph and other x-intercept.
Answer to Problem 13CFU
Three additional points on the graph are
The other x-intercept is
Explanation of Solution
Given information:
The equation is as follows:
Points on graph equation are
Point on x-intercept is
Calculation:
Put
If the solution of equation is same as that of any other case, then their graphs are symmetric.
Let’s check whether the given cases are symmetric with the given equation or not by substituting replacing
Check symmetry with | Symmetric with graph equation (Yes/No) | ||
x-axis | Yes | ||
y-axis | Yes |
Since the graph is symmetric to y-axis, so the another x-intercept is
Since the graph is symmetric to x-axis also, so any value of y can give the same value of x. Thus, other two points can be
