function. Give the domain and range.

(a) f(x) = -2x + 1

(b)f(x) = -3.

Use the following points for graphing:

(-2,5), (0,1), (2,-3).

Domain = All real valus of X.

b. F(x) = Y = -3.

Since Y is constant(-3),X is varying.

Therefore, we have a hor. line; and Y

equals -3 for all values of X.

(-2,-3), (0,-3), (2,-3).

Domain = all values of X.
