Answer:2
Step-by-step explanation:
I have the problem on my my review and it says 2
Substituting the given values of X into the function, the value of f(3) - f(4) is 2
Given the function :
- f(x) = - 2x + 3
f(3) = - 2(3) + 3
f(3) = - 6 + 3 = - 3
For X = 4 :
f(4) = - 2(4) + 3
f(4) = - 8 + 3 = - 5
f(3) - f(4) = - 3 - (-5)
f(3) - f(4) = - 3 + 5 = 2
Therefore, the value of f(3) - f(4) is 2
