Two roots of a third degree polynomial function f(x) are 4 and 4. Which statement describes the number and nature of all roots for this function?
O f(x) has three imaginary roots.
Of(x) has three real roots.
Of(x) has two real roots and two imaginary roots.
Of(x) has three real roots and one imaginary root.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

-1/3(x+1)^5

i’m pretty sure this is correct

yeah i know the problem you need. i am taking it right now. the answer is step 3
