If f(x) = 3x^2 + 2x, then find the value of y when x = -1.

1

Step-by-step explanation:

-1 to the power of 2 is 1

1 times 3 is 3

2 times -1 is -2

3+(-2)=1

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)
