We have the following functions:
f (x) = x ^ 2 + 1
g (x) = 1 / x
Multiplying we have:
(f * g) (x) = (x ^ 2 + 1) * (1 / x)
Rewriting:
(f * g) (x) = ((x ^ 2 + 1) / x)
Therefore, the domain of the function is given by all the values of x that do not make zero the denominator.
We have then:
All reals except number 0
Answer:

Answer:
Rhian did better in the Math test.
Step-by-step explanation:
Given: Rhian scored
out of
in a Math test. In the English test she scored
out of
.
To find: In which test did she do better?
Solution:
We have,
Rhian scored
out of
in a Math test.
Rhian scored
out of
in an English test.
So, first we need to find the percentage of the marks scored.
Percentage in the Math test
.
Percentage in the English test
.
Clearly, the percentage in the Math test is greater than the percentage in the English test.
So, Rhian did better in the Math test.
