Maybe the answer would be 12/5
It would be f(x) = 2(x+1)^2 + 7, hope this helps :)
<u>Answer:</u>
No, the given set of pairs does not represent a function
<u>Step-by-step explanation:</u>
For a set of values to be a function, each input must have one and only one output value
Now, for the given set, we can note that:
The input -13 has two output values; 4 and 9

Hope this helps :)
F=EA(e/l)
e/l=EA/F
l=Fe/EA
