Answer:
Domain x ∈ R
Range y ∈ R
Step-by-step explanation:
Since the radical function have its exponential odd, there are no restrictions in what result should have in order to not obtain a complex value, that is why the domain is every real number (x ∈ R)
Now, to obtain the range, we have to determine possible values for 'y' variable. Since there are no restrictions in domain, and the function y=
doesnt have limits, we can say that y also belongs to all real domain.

Thank u so much have a good day too
Answer:
The student took the numbers for the factors 5, -4 for the zeros instead of solving the equation
The zeros are -5, 4
Step-by-step explanation:
x^2 +x - 20=0
What 2 number multiply to -20 and add to 1
5*-4 = -20
5+-4 = 1
(x+5)(x-4) =0
Using the zero product property
x+5 = 0 x-4 =0
x=-5 x=4
