Sketch the graph of each linear
function. Give the domain and range.
(a) f(x) = -2x + 1
(b)f(x) = -3.
a. F(x) = Y = -2X + 1.
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.
