HELP PLESSE ITS MULTIPLE CHOICE

Step-by-step explanation:

First of all, we have to solve all the equations

First one is (4*1)-6

We have to use PEMDAS

which stands for

Parenthesis

Exponents

Multiplication

Divison

Addition

Subtraction

In (4*1)-6  

You have to do 4*1 first ~ which equals 4

the next step would be 4-6  ~  which equals -2

The next equation would be (1*4)-6

First do 1*4  ~ which is 4

Next 4-6  ~ which again equals -2

Next equation is (1*6)-(4-6)

Parenthesis first, 1*6=6

4-6=-2

6-(-2)

which equals 8

Our next equation is 6-(1*4)

1*4=4

6-4~ which equals 2

Our last equation is 4*(1-6)

Parenthesis comes first, so it would be 1-6 first

which equals -5

4*(-5) would be our final step  ~  which equals -20

All of our answers would be

-2 - from the top equation

-2 - from letter A

8 - from letter B

2 - from letter C

-20 - from letter D

which means Letter A is the answer.

Hope this is helpful.

the f

last graph i believe

step-by-step explanation:

worked it out i believe

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
