Question

Given the function f(x) = (5x + 215) / 728, find f(9).

a) 7/12
b) 5/14
c) 1/7
d) 3/14

Answer 1

To find the value of f(9), substitute 9 into the given function and simplify the fraction.

Step-by-step explanation:

To find the value of f(9), we need to substitute 9 into the function f(x) = (5x + 215) / 728. So, we have:

f(9) = (5 * 9 + 215) / 728

f(9) = (45 + 215) / 728

f(9) = 260 / 728

Now we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 4. So:

f(9) = 65 / 182
