Is this right ? Im honestly confused
fgiga [73]

Answer:

In step by step

Step-by-step explanation:

For #1, everything is perfect.

For #2, you wrote your functions out incorrectly, but your x input and y output are correct

#3 is a little messed up.

Your function is f(x)=-3x+1. Your given x's are -3, -1, 0, 1, 2, and 3. Plug all of these in.

1. f(-3)=-3(-3)+1

  • f(-3)=9+1
  • f(-3)=1

2. f(-1)=-3(-1)+1

  • f(-1)=3+1
  • f(-1)=4

3. f(0)=-3(0)+1

  • f(0)=0+1
  • f(0)=1

4. f(1)=-3(1)+1

  • f(1)=-3+1
  • f(1)=-3

5. f(2)=-3(2)+1

  • f(2)=-6+1
  • f(2)=-5
