Sketch a graph of the following function.
f(x)=\frac{1}{-1x+2} 
Where are the vertical asymptotes?

campbell_st · Answer

so is the equation 

$$f(x) = \frac{1}{-x + 2}$$

anonymous · Answer

yup

campbell_st · Answer

ok.. so the vertical asymptote exists when the denominator is zero so solve 

-x + 2 = 0

this will be the asymptote

anonymous · Answer

but how? i dont really understand it...o.o

campbell_st · Answer

ok... so if a fraction has a zero denominator its undefined... 

or... you can't divide anything by zero.... there is no answer.... 

so that is what you are looking for the value of x that makes the denominator 
zero

anonymous · Answer

ok, so i just graph the asymptote?

campbell_st · Answer

show the asymptote as a dotted line and then graph the functions... its hyperbolic

and it looks like

lol alright, i see. thank you! :D
