Answer:
-1.5
Step-by-step explanation:
3/8 is 0.375 in decimal form
The domain of a function is where we have a value for x.
Since that's the case the domain of f(x) = {x e R / 1 ≤ x < 5}
We see that we have a value for x = 1 cuz we have a filled circle, but we don't have a value for x = 5, look at the unfilled circle
So, our x can vary between 1 and 5, but can't be 5.
Either you can use distributive property or you can add up the numbers in the brackets.
Hopefully that helped! :)
