The difference between the given expression is -255/16
Functions are written in terms of variable. For instance y = f(x) is a function of y.
Given the expression below
a^2-b^4
Given the following parameters
a= -1/2 and b=2.
Substitute the given parameters to have:
(-1/2)^2 - 2^4
Expand the resulting expression to have:
(1/16) - 16
(1-256)/16
-255/16
Hence the difference between the given expression is -255/16
