I don't understand how to find the answer...

Answer 3

the choices are: Increasing x > 0; Decreasing x <0

Decreasing on all real numbers

INcreasing on all real numbers

Answer 12

Would it be only increasing? I don't understand how to read the graph and answer with x > 0 or x <0

Answer 13

Answer 14

Check the graph, with increase in x is there increase in y (or f(x))?

Answer 15

I believe that there is only an increase so the y must also increase as well right? if was going to be a decrease, then the increase for x would be the decrease for y correct?

Answer 16

also i don't understand when they use f(x) and f(x) = f(-x), i get confused with the number < x < number

Answer 17

Ok, I will explain that doubt later

Answer 18

Okay, but since the graph is only increasing then would it be increasing on all real numbers?

Answer 19

Sorry

Answer 20

So the answer would be increasing on all real numbers since it is only increasing?

Answer 21

As you move right, the graph rises.
Which means as x increases, y increases. For x=0, there are many values of y but slope of line >0, so it's increasing at x=0 as well.
So it's increasing for all real numbers

Answer 22

Okay, i think i understand it a bit more :)
