    Answer:  The required match is given by

    f(-1) = -6,

    f(0) = -5,

    f(1) = -4,

    f(2) = -3,

    f(5) = 0,

    f(8) = 3.

    Step-by-step explanation:  We are given a function f(x) defines as follows :

    f(x)=x-5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

    We are to match the given values.

    If x = -1,  then from equation (i), we get

    f(-1)=-1-5=-6.

    If x = 0,  then from equation (i), we get

    f(0)=0-5=-5.

    If x = 1,  then from equation (i), we get

    f(1)=1-5=-4.

    If x = 2,  then from equation (i), we get

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

    If x = 5,  then from equation (i), we get

    f(5)=5-5=0.

    If x = 8,  then from equation (i), we get

    f(8)=8-5=3.

    Thus, the required match is given by

    f(-1) = -6,

    f(0) = -5,

    f(1) = -4,

    f(2) = -3,

    f(5) = 0,

    f(8) = 3.

    Substitute the values of x to the equation of a function f.

    f(x) = x – 5

    f(-1) = -1 – 5 = -6 ≠ 0

    f(0) = 0 – 5 = -5 ≠ 3

    f(1) = 1 – 5 = -4   🙂

    f(2) = 2 – 5 = -3   🙂

    f(5) = 5 – 5 = 0 ≠ -5

    f(8) = 8 – 5 = 3 ≠ -6
