What is the function?

C. f(x)= 0.5(3ˣ)

Step-by-step explanation:

C. f(x)= 0.5(3ˣ) is the function as per table

C

Step-by-step explanation:

For the exponential function in the form

y = a

Use ordered pairs from the table to find a and b

Using (0, 0.5 ), then

0.5 = a ( = 1 ), thus

0.5 = a

y = 0.5

Using (1, 1.5 ) , then

1.5 = 0.5 , hence

b = = 3

Thus

f(x) = 0.5 → C

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)

answer4 to the second power is 16

and 4 to the third power is 64,
