This is even function because
1)the ends are looking in one side, both are up
2)You can see that it has line symmetry y
3) for any point
f(x)=f(-x)
f(1)=-6
f(-1)=-6
Answer:
All except one interval [-2,8]
Step-by-step explanation:
Notice that the function, wich an hyperbola, has a vertical asymptote in both -2 and 8 and there is nothing between this two values.
So we will exclude what's between them out of the domain.
Answer:
