Question 63983
QUESTION:


for the function y= 1/x-1, give the y values for x=-2, -1, 0, 1, 2, 3. Using these points, draw a curve and show the graph.


ANSWER:

The function is 


y = 1/x-1  ( as the function is not clear, I  take the equation as (1/x)-1 )


Values of x is given as,   x = -2, -1, 0, 1, 2, 3. 




Input these values in the given equation.


When x = -2 ,    y = (1/-2) -1 = -0.5 -1 =  -1.5




When x = -1 ,    y = (1/-1) -1 = -1 -1 =  -2



When x = 0 ,    y = (1/0) -1 = 0 -1 =  -1



When x = 1,    y = (1/1) -1 = 1 -1 =  0



When x = 2 ,    y = (1/2) -1 =0.5 -1 =  -0.5



When x = 3 ,    y = (1/3) -1 = 0.3 -1 =  0.7




Using these  points, plot the graph.



Then it comes like this,





{{{ graph( 700, 700, -15, 15, -15, 15, (1/x) - 1) }}}







Hope you understood.
