can you show me all the points for f(x) and the domain and range?

Question

graph f(x)=1/x

 

x=-5 , -1, -1/2 ,0 , 1/2 , 1, 5

F(x)=

Answer 1

Ralph, I'll do the first one. All you are doing is plugging in the given x for x in the equation.

 

f(-5) = 1/-5 = -1/5. The point is (-5, -1/5).

 

Graph it and the rest. The domain is how far left and right the graph goes, and the range is how high and low the graph goes.
