Sketch the graph of each linear

function. Give the domain and range.
(a) f(x) = -2x + 1

(b)f(x) = -3.

1 answer

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.
