Answer:

The answers are as follows for the functions.

f(1) = 12

f(3) = 22

f(5) = 32

Step-by-step explanation:

To find any of these, simply input the value in for x in the equation given.

f(1)

f(x) = 5x + 7

f(x) = 5(1) + 7

f(x) = 5 + 7

f(x) = 12

You can repeat this for each of them and it will allow you to use all of the numbers in the equations given.

Answer:

Option C is correct

f(1)-f(3) =f(3)-f(5)

Step-by-step explanation:

Consider the function:

f(x) =5x+7

At x = 1

f(1) =5(1)+7=5+7=12

⇒f(1) = 12

At x = 3

f(3) =5(3)+7=15+7=22

⇒f(3) = 22

At x = 5

f(5) =5( 5)+7=25+7=32

⇒f(5) = 32

At x = -1

f(-1) =5(-1)+7=-5+7=2

⇒f(-1) = 2

At x = -3

f(-3) =5(-3)+7=-15+7=-8

⇒f(-3) = -8

A.

f(1)-f(3) =f(3)-f(1)

⇒12-22 = 22-12

⇒-10= 10

Option A is incorrect.

B.

f(1)-f(3) =f(5)-f(3)

⇒12-22 = 32-22

⇒-10= 10

Option B is incorrect.

C.

f(1)-f(3) =f(3)-f(5)

⇒12-22 = 22-32

⇒-10= -10

Option C is Correct.

D.

f(1)-f(3) =f(-1)-f(-3)

⇒12-22 = 2-(-8)

⇒-10= 10

Option D is incorrect.
