z(-3)
what's the question?
-3z
To evaluate the expression z(-3), we need to know what z represents. Without that information, it is not possible to determine the value of z(-3).
However, if z represents a function or variable, and you have information about z and its relationship to (-3), you can substitute -3 into the function or variable to find the answer.
For example, if z is a function defined as z(x) = 2x + 1, then to evaluate z(-3), you substitute -3 for x in the function: z(-3) = 2(-3) + 1 = -6 + 1 = -5.
In summary, to evaluate an expression like z(-3), you need to know what z represents and any necessary information about its relationship to (-3).
