The half-life of a radioactive material is the amount of time it takes for 50% of its radioactivity to decrease. If a particular material has a half-life of
35 years, then what percent will remain radioactive after 100 years?
(1) 13.8%
(3) 34.8%
(2) 22.7%
(4) 48.7%

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

vertical asymptote .

horizontal asymptote .

step-by-step explanation:

given function is .

vertical asymptote is given by setting

denominator =0

when degree of numerator and denominator are same then divide first term of numerator by first term of denominator to get horizontal asymptote.
