∑[1/(3^(n-1))] represents the series 1+1/3+1/9+1/27+1/81+1/243 using sigma
notation. I am hoping that this answer has satisfied your query and
it will be able to help you in your endeavor, and if you would like, feel free
to ask another question.
<span>x = –4c
</span>if c = -2 then x = -4(-2) = 8
I believed you had a typo, function should be f(x) = -3x^2 - 4x
so
<span>f(x) = -3x^2 - 4x
</span>f(x) = -3(8^2) - 4(8)
f(x) = -3(64) - 32
f(x) = -192 - 32
f(x) = -224
answer
<span>C.
–224</span>
