If a(x) = 3x + 1 and 5(x)=1/x-4, what is the domain of (ba)(x)?

kumpel [21]

For this case we have the following fusions:

$a (x) = 3x + 1\\b (x) = \frac {1} {x} -4$

We must find $(a * b) (x):$

By definition:

$(a * b) (x) = a (x) * b (x)\\(a * b) (x) = (3x + 1) * (\frac {1} {x} -4)\\(a * b) (x) = \frac {3x} {x} -12x + \frac {1} {x} -4\\(a * b) (x) = 3-12x + \frac {1} {x} -4\\(a * b) (x) = - 12x + \frac {1} {x} -1$

The domain of the function will be given by all the values for which the function is defined, that is, all real numbers except zero.

Noelle and karina both leave the Internet cafe at the same time, but in opposite directions. If karina travels 9 mph faster than

Vesna [10]

Noelle goes east at N mph.
Karina travels west at N + 9
then their velocity between them is (N + N + 9)
After 8 hours they travel 8(2N + 9) = 232
(2N + 9) = 29
2N = 20
N = 10 mph for Noelle
N+9=19 mph for Karina
