If f(x) = 3 – 2x and g (x) = StartFraction 1 Over x + 5 EndFraction, what is the value of (StartFraction f Over g EndFraction) (

vredina [299]

For this case we have the following functions:

$f (x) = 3-2x\\g (x) = \frac {1} {x + 5}$

We must find: $\frac {f} {g} (8)$

By definition we have to:

$\frac {f} {g} (x) = \frac {f (x)} {g (x)}$

So:

$\frac {f (x)} {g (x)} = \frac {3-2x} {\frac {1} {x + 5}} = (3-2x) (x + 5)$

Thus, we have to:

$\frac {f} {g} (8) = (3-2 (8)) (8 + 5) = (3-16) (13) = - 13 * 13 = -169$

So, the value is -169
