1 answer:
Step-by-step explanation:
I don't see really the actual answer options (you made a bad copy here).
so, I can only tell you what it is in my own terms and you need to associate to the actual answer option.
based on real numbers (not complex or imaginary) we cannot use the square root function on negative numbers.
the domain defined what values can be used for x.
so,
0<= x < +infinity

Answer:
4x^2 + 11x - 20
Step-by-step explanation:
area is width X height multiply the width (4x - 5) and the height(X + 4) I always imagine a multiplication grid for this kind of problem, with X and +4 at the top and 4x and -5 going down, and then combine terms you get 4x^2 + 11x - 20
I think it's Real numbers
Y= -1/5 x+ 6
