A function is a special relation whose every input corresponds with a single output. To be a function, each input is allowed to pair with only one output element.
For a parabola equation like above, there is no restriction in the domain. For every x value there is a unique y value.
Conclusion:
The equation is BOTH <u>a function and a relation</u>!
The solution would
be like this for this specific problem:
ab/a+b = c
b = -1 + a
for c:
<span>(5(-1 + 5))/(5 + (-1 +5))
</span><span>5(4)/ 5 + 4
</span><span>20 / 9
</span>
<span>The correct
answer between all the choices given is the first choice or letter A. I am
hoping that this answer has satisfied your query and it will be able to help
you in your endeavor, and if you would like, feel free to ask another question.</span>
