3 to the 4th power = 3x3x3x3 which is 81 :)
Answer:
i don't know a counterexample for the first one
A counterexample for the second one is a leaf bug
A counterexample for the third one is a trapezoid, rectangle, rhombus
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:
b. all real numbers, except 0
