Find f(x) if it is known that f(x+3)=5x+15.

victus00 [196]

Answer:

The function is "f(x) = 5*x"

Step-by-step explanation:

Everytime we add a number to the independent variable of a function, in this case x, there'll be a common factor between the variable and a pure number. To solve this problem we need to make "(x + 3)" appear. Since we have "f(x+3)" we need to first factor the common denominator. We have:

f(x + 3) = 5*(x + 3)

Therefore,

f(x) = 5*x

$= 10 {}^{2} + 20 {}^{2} - 5! \\ = 100 + 400 - \\ (5 \times 4 \times 3 \times 2 \times 1) \\ = 100 + 400 - 120 \\ = 500 - 120 \\ = 380$
