If f(x) = 2x and g(x)=1/x, what is the domain of (fg)(x)

Mathematics

Answer:

The domain is all real numbers except the number zero

Step-by-step explanation:

we have

f(x)=2x

g(x)=\frac{1}{x}

we know that

(fg)(x)=f(g(x))=2(\frac{1}{x})

Remember that

The denominator cannot be equal to zero

so

The domain is all real numbers except the number zero

In Interval notation the domain is

(-∞,0) ∪ (0,∞)

It rain 10% of the 30 days last month. On how many days did it not rain?
alexdok [17]
Ok. You need to find the 10% of days it did rain. Since there were 30 days, ten percent of that would be 3 days. So it rained three days. If there were 30 days, then 30-3=27 days it did not rain.
