If it is asking if that equation is the quadratic formula, then the answer is false. The reason why is that the first 'b' should be negative
The quadratic formula is

1)16^2 or 4^4
2)3^2
3)4^2
4)5^2
5)15^2
6)14^2
The equation has a slope of -2/3 and a Y-intercept of -1.
So the first graph should be your answer
The answer would be 1/64 if the power of the bracket is -1(I am not sure if the question shows -1 as I can't see clearly).Sorry and Hope this will help
