Answer:

2

Step-by-step explanation:

Step 1: Solve for f(3)

  • f(3) = -2(3)+3
  • f(3) = -6 + 3
  • f(3) = -3

Step 2: Solve for f(4)

  • f(4) = -2(4) + 3
  • f(4) = -8 + 3
  • f(4) = -5

Step 3: Subtract f(4) from f(3).

  • f(3)-f(4)
  • (-3)-(-5)
  • -3 + 5
  • 2

Therefore, the answer is 2.

Answer:

2

Step-by-step explanation:

F(3) means that we plug in 3 for the x value of the original equation, and F(4) means that we plug in 4 for the x value of the original equation

F(3) = -2(3) + 3

= -3

F(4) = -2(4) + 3

= -5

- 3 -(-5) = 2
