Hi

I'm a Belgian CLIL teacher and I'm teaching CLIL maths since September.

Next week I want to start with functions, but I have the problem I can't translate some things.

Can someone please help me what the name is in English?

1) First one is a kind of scheme/table where you can say if a function goes up or down.

It looks like this for a linear function (the arrow goes to the right and up if the function/line goes up and the arrow goes to the right and down if the function/line goes down):

x |

--------------------

f(x) | -->

2) The second one is a kind of scheme/table where you can say if a function is positive or negative.

This example is when the zero of the function is (5,0) and the straight line goes up.

x | 5

--------------------

f(x) | - 0 +

Meanwhile I already found the word sign table.

But how do you call increasing, decreasing... in one word? The ... of a function. In Dutch we call it "verloop", but it's the same like process..., but what's the right mathematical term?
