F (x) = 3x + 1 ; g (x) = 3x What is f (g (x) )

f(g(x)) = 9x + 1

Step-by-step explanation:

f(x) is defined as 3x + 1.  To find f(g(x)), substitute g(x) = 3x for x in f(x):

f(g(x)) = 3(g(x)) + 1 = 3(3x) + 1 = 9x + 1

or:

f(g(x)) = 9x + 1

step-by-step explanation: hi!

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
