Find the limits of a, b, c for the function f(x) = 3x/x-4 use neg. infinity and infinity where appropriate?

lim f(x)


x-%26gt;4 -





lim f(x)


x-%26gt;4+





lim f(x)


x-%26gt;4

Find the limits of a, b, c for the function f(x) = 3x/x-4 use neg. infinity and infinity where appropriate?
first one is negative infinity since when you approach 4 from the left, x - 4 %26lt; 0





second one is positive infinity





third is undefined since the left limit does not equal the right limit
