Find (f-g)(x) for f(x)=4x-9 and g(x)=3x^2

Step-by-step explanation:

x=-0.93 or 2.265

jxt solve like quadratic equation

4x-9-3x^2

Step-by-step explanation:

Fill in the expressions for f(x) and for g(x). You get the answer provided. It doesn't have to be put in descending order in this instance because you're doing exactly what it asked, f(x) - g(x).

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)
