Excluded values

Question

Determine which value(s) are excluded from the domain and range of f(x)=−2/x+2.

Answer 1

For the function f(x)=−2/x+2,

x = 0 is excluded from the domain and y = 2 is excluded from the range.

__________________________________________________________________________________

If the function is f(x) = -2/(x+2)

then x = -2 is excluded from the domain and y = 0 is excluded from the range
