Answer:
x=30
Step-by-step explanation:
(3x-10)+(2x-20)=180// 5x-30=180//5x=150//x=30
The equation is false because the real answer is z5/4. The variable doesn't just disappear.
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
