Answer:

The value of f(-3) is 21

Step-by-step explanation:

f(x)= 2x^2-x

we need to find out f(-3) using the given f(x)

f(-3) means x is -3, plug in -3 for x

f(x)= 2x^2-x

f(-3)= 2(-3)^2-(-3)

f(-3)= 2(9)-(-3)

f(-3)= 18+3= 21

The value of f(-3) is 21

Any questions 1-4 help me please
ASHA 777 [7]
For Q2 it is just a simple matter of using a tree diagram for each possible outcome. So there are 4 black balls (B) and 2 white (W) and by using a tree diagram of the possible outcomes it comes to a 3 out of 5 points go to player 1 if B was drawn first and 2 go to player 2. If W was drawn first though, then player 1 gets 1 out of 5 points and 4 goes to player 2 and if you add up the probabilities at the end it comes to player 1 having a 14 out of 30 chance and player 2 having a 16 out of 30 chance therefore player 2 would have a better chance at winning and it isn't a fair game
