Answer:
It is a function
Step-by-step explanation:
This isn't really a step by step explanation but I'm going to explain this simply. An output can have as many inputs possible but an input can only have ONE OUTPUT(just putting emphasis on this one output, I'm not yelling). Example, the input "2" can be equal to the output of "4" depending on the equation the fuction, however, the input of "2" CAN NOT be equal to the outputs of "4" and "6" because as my Algebra teacher explained it "for every input, there is exactly one output". I hope this helps and I hope I didn't lose you in my explaination.
The answer is:
an=4000n+38,000
Sam has $42,000 one year after graduating. So when he graduates, he would have $38000.
Hope this helps!

square root of (4x+41)=x+5
4x+41>=0
x >= -10.25
(square root of4x+41)^2=(x+5)^2
4x+41=x^2+10x+25
x^2+6x-16 =0
x +8
x -2
(x+8)(x-2)=0
x= -8
x= 2 extraneous
