Why are linear functions sometimes symmetric about the y-axis but never symmetric about the x-axis
lina2011 [118]
Test for symmetry about the x-axis: Replace y with (-y). Simplfy the equation. If the resulting equation is equivalent to the original equation then the graph is symmetrical about the x-axis. Example: Use the test for symmetry about the x-axis to determine if the graph of y - 5x2 = 4 is symmetric about the x-axis.
Test for symmetry about the y-axis: Replace x with (-x). Simplfy the equation. If the resulting equation is equivalent to the original equation then the graph is symmetrical about the y-axis. Example: Use the test for symmetry about the y-axis to determine if the graph of y - 5x2 = 4 is symmetric about the y-axis.

Which mathematical symbol would best fill in the blank to compare the two real numbers?
Alexandra [31]

Answer:  The correct option is (A) < .

Step-by-step explanation:  We are given to select the correct mathematical symbol that would best fill in the blank to compare the following two real numbers :

\sqrt7~~~?~~~\dfrac{14}{5}.

First , we need to find the values of both the real numbers in decimal form.

We have

\sqrt7=2.64575...,\\\\\dfrac{14}{5}=2.8.

Since, 2.64575 so we get

\sqrt7

Thus, the correct mathematical symbol is <.

Option (A) is CORRECT.
