Question

Find the value of f(x) = 9x/(5 - x).

a) f(x) = -9/5
b) f(x) = 1 - x
c) f(x) = 9/(5 - x)
d) f(x) = 9x/(5 - x)

Answer 1

The value of f(x) = 9x/(5 - x) can be found by substituting the given value of x = 3 into the function. The value of f(x) when x = 3 is 13.5.

Step-by-step explanation:

The value of f(x) = 9x/(5 - x) can be found by substituting the given value of x = 3 into the function. Here's how:

1. Replace x with 3 in the function: f(3) = 9(3)/(5 - 3) = 27/2 = 13.5

Therefore, the value of f(x) when x = 3 is 13.5.
