Answer:
Step-by-step explanation:
Write the system
Solve by Elimination.
multiply the second equation by -3.
Add the Equations.
Plug this back in one of the equations.
This set notation really seems the hard way to exclude a single value. Anyway...
The domain doesn't include where the denominator is zero, 4x + 7 = 0,
x = -7/4
The range doesn't include the asymptotic value, which is
y=2x/4x = 1/2
So we need domain x ≠ -7/4 and range y ≠ 1/2
