Name the Vertical and Horizontal Asymptotes. f(x) = 2/x-1 +4
f(x) has a vertical asymptote at x = 4 and a horizontal asymptote at y = 1
Of(x) has a vertical asymptote at x = 1 and a horizontal asymptote at y = -4
O f(x) has a vertical asymptote at x = 1, but no horizontal asymptote
Of(x) has a vertical asymptote at x = 1 and a horizontal asymptote at y = 4

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
