A. f(-2) = 8-4(-2)
B. 8-4x = 9
You have two points now. plot them and draw the line between them
A line goes forever in both directions, both horizontally and vertically, so ...
now look up the points for E and F
Given: f(x) = 8 - 4x
A. Find f(-2)
B. Find x, when f(x) = 8
C. Graph the function.
D. State the domain and range of the function.
E. Use the graph to find x, when f(x) = 0. Show details on the graph.
F. Use the graph to find f(x) when x = 3. Show details on the graph.
