Can someone show an example of Inverses of Functions
Because I do not understand that subject

I believe you mean algebra and inverses when you change it to solve inequalities.

Step-by-step explanation:

Let's use -3 + 4 as an example. In order to change the function, you will switch the sign. (In this case, we change "+" into ")

At this same time, you must change the sign in front of the numbers. (Positive signs become negative and negative signs become positive.

So, -3 + 4 is the same thing as 3 - -4.

3 - 4 = -1

-3 + 4 = 1

Tip: When subtracting a negative number, the answer is likely to go up instead of down.

I hope this helps! I did my best :)

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
