Using f(x) = 5x + 4 and g(x) = x - 3,find: 1. f(g(6)) 2. g(f(-7)) 3. f(f(8)) 4. g(f(x))

Part 1):

Part 2):

Part 3):

Part 4):

Step-by-step explanation:

Considering the function

Part 1)

To evaluate , you must find

so

Put x = 6

Then  

Therefore,

Part 2)

To evaluate , you must find

so

Put x = -7

Then  

Therefore,

Part 3)

To evaluate , you must find

Put x = 8

Then

Therefore,

Part 4)

Evaluate

As

so

Therefore,
