Hi there.
The answer is g(1) = 3
Explanation:
Find the function that has x = 1 as a part of the domain. That is the second function that has x = 1 as a part of domain.
For the first function, the domain is lesser than or equal to -1, therefore, x = 1 isn't the part.
For the third function, the domain is greater than or equal to 2, meaning x = 1 isn't also the part of the domain as well. That leaves only the second function where -1 < x < 2 as x = 1 is the part.
Thus, our main function is —
Then evaluate the value of g(x), substitute x = 1 in the equation. However, the function doesn't have x-term.
Thus, answer the constant number.
Therefore,
Answer:
Step-by-step explanation:
When you have exponents above a like term and they are being multiplied together, you add them.
For example:
So let's group like terms in the numerator:
We can add terms like in the example.
Let's rearrange the denominator.
Now we have:
Cancel like terms
4/8 = 1/2
= 1 So it cancels
= s Since s is raised to the -1 it goes on top and becomes s.
Now we combine everything back together:
