Question

If f(x) = x - 5, then match each of the following.

1. f(-1) 0
2. f(0) 3
3. f(1) -4
4. f(2) -3
5. f(5) -5
6. f(8) -6

Answer 1

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

Answer 2

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.
