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
