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

(b)f(x) = -3.

  • m-100 - ,

    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.
