Use three different ways (graph, table, algebraically) to convince someone that

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

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.

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?

I'll make those posts invisible...and I agree....you shouldn't be attacked...just because it might be easy for others doesn't mean that it's easy for everyone....
