I'll focus on one example:    f(x)=x^2:    (-2,f(-2)) and (0,f(0)) 4)

Find the average rate of change of f(x) = x^2 from x = -2 to x = 0:
f(0) - f(-2)           (0)^2 - (-2)^2)         0-4
arc = =  = = -2 (answer)
0-(-2)                         2                    2

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

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.

The value of the function f(x) at each point is f(-1) = 5, f(0) = 3, f(1) = 5, f(2) = 11, f(3) = 21 ⇒ A

Step-by-step explanation:

Let us use the mapping shown to solve the question

∵ f(x) = y

∵ x is the domain

∵ y is the range

→ From the figure use x from the domain and y from the range, where

each arrow pointed at the corresponding value y of x

∵ x = -1 and the corresponding value of y is 5

∴ f(-1) = 5

∵ x = 0 and the corresponding value of y is 3

∴ f(0) = 3

∵ x = 1 and the corresponding value of y is 5

∴ f(1) = 5

∵ x = 2 and the corresponding value of y is 11

∴ f(2) = 11

∵ x = 3 and the corresponding value of y is 21

∴ f(3) = 21

The value of the function f(x) at each point is f(-1) = 5, f(0) = 3, f(1) = 5, f(2) = 11, f(3) = 21

1. f(x)=1/2x-3     f(x)=1/2x-3

f(0)=1/2(0)-3   f(6)=1/2(6)-3

f(0)=-3             f(6)=0

m=f(b) - f(a)/b - a = 0- (-3)/6 - 0  = 3/6 = 1/2

2.  f(x) = -x         f(x) = -x

f(-4) = -(-4)    f(2) = -2

f(-4) = 4         f(2) = -2

m=f(b) - f(a)/b - a = -2 - 4/2 - (-4) = -6/6 = -1

3. f(x) = x^2     f(x) = x^2

f(-2) = -2^2  f(0) = 0^2

f(-2) = -4      f(0) = 0

m=f(b) - f(a)/b - a = 0 - (-2)/0 - (-2) = 2/2 = 1

4. f(x) = x^3     f(x) = x^3

f(-1) = -1^3  f(1) = 1^3

f(-1) = -1      f(1) = 1

m=f(b) - f(a)/b - a = 1 - (-1)/1 - (-1) = 2/2 = 1

5. f(x) = 2^x    f(x) = 2^x

f(0) = 2^0    f(4) = 2^4

f(0) = 1        f(4) = 16

m=f(b) -f(a)/b - a = 4 - 0/ 4 - 0 = 4/4 = 1

i hope this is right, have a good day
