Answer:
Step-by-step explanation:
we have
Solve for x
Applying difference of squares in the denominator of the second term in the left side

Apply the distributive property in the left side
Combine like terms left side
Group terms
Divide by 3 both sides
Answer:
a) .
Substitute all the values in the given relation.
The steps and table is attached below.
b) The relation is not a function.
Since the x =0 and x=3 has the same value. A relation is function when each input has only exact one output. refer the on-to diagram uploaded.
c) The domain is the set of all input values that can be applied into a function y or f(x).
Here all the x values -4,-3,-,-1,0,1,2,3,4 [-4,4] is the domain.
