In case of graph, for domain we consider all the x values.
Domain is all input values for which we get a real output or all possible x values for which we get real y values.
here from the graph we can see the possible x values are all real numbers from 0 to 8.
So option A is correct.
To solve the system
you have to add both equations:
.
Substitute this x-value into second equation:
.
The solution of the system is x=14/3 and y=2/3.
Answer: y=2/3, correct choice is B.
do u still need the answer?
Answer: its not :)
