u should be able to subtract off the plot but if not you have to trace them with invertables

The negative sign on an exponent means the reciprocal. Think of it this way,

just as a positive exponent mean repeated multiplication by the base, a negative exponent means repeated division by the base.

Example

So 2^ (-4)= 1 / (2^4)=1/(2*2*2*2)=1/16

So that answer would be 1/16
