Question

Given: f(x) = 8 - 4 x


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.

Answer 1

f (-2)=8-4×-4=+16
f(x)=8 so 8 =8-4x so x=0
it is liner algebra . I will send you the graph and every thing later . like in 5 min .
