+73 Use three different ways (graph, table, algebraically) to convince someone that
+128408 Graph : This is symmetric with the y axis....this is characteristic of an even function
Graph here : https://www.desmos.com/calculator/w76y3q8fup
Table
x y
1 4
-1 4 this is also characteristic of an even function... if (-x, y) is on the graph....then so is (x , y)
Algebraically
If f(x) = f(-x)....then even
f(x) = x^2 + 3
f(-x) = (-x)^2 + 3 = x^2 + 3 = f(x)...so.....even
+73 Thanks, CPhill! Also, can you check my work if it is correct? It was a post from a few days before but I just forgot to respond back. There is also have been some guests insulting me for no reason what so ever. Maybe you should check on it.

+128408 Just ignore these people....remember....their words can't hurt you on here !!!
And..I'll check...
+73 Thanks, I understand it now. I have been struggling with these kinds of problems for a certain reason which is stressing me. I don't know why people on this forum are attacking me just for posting math here when I didn't do anything to others. Can you like delete those messages knowing that you're a moderator?
