Let f(x) = 3x - 6 and g(x) = x - 2. Find f(g(5)) - ie. (f o g)(5) and its domain

1 answer:

4 0

Do this by finding g(5) first. Replacing x with 5 in g(x) gives you that g(5) = 3. Now replace that 3 in the x in f(x) to get that f(3) = 3. As far as the domain goes,, they are both lines and the domain for lines is all real numbers.

Iteru [2.4K]

Step-by-step explanation:

Find 1% of 75

$6.75 * 4 = $27

$75 - $27 = $48

The stock was $48 in 2016
