Given that ƒ(x) = x2 + 1 and g(x) = –3, multiply the functions (g · ƒ)(x). Question 9 options: A) (g · ƒ)(x) = –3x2 + 3 B) (g · ƒ)(x) = 3x2 – 3 C) (g · ƒ)(x) = –3x2 – 3 D) (g · ƒ)(x) = 3x2 + 3

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)
