For which value of x does the graph of the following function f(x) have a vertical asmptote? f(x)=3/x+5
a.-5
b.-3
c.3
d.5

set the denominator = 0 then solve for x

x+5=0

x=-5

b

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
