thank you sir. Naturalwaves, seen your reply too..thank you.

A woman is four times old as her daughter. In four years time she will be three(3) times old as her daughter. What are their ages?

Naturalwaves, dejt4u and others help plzz! Been solving it over and over since yesterday but my answer doesn't seem to be correct

abiodun3934:
pls help me solve this question i need it urgently :let a function f be defined by f(x)=x^2-2x-3/x^2+2x+3 hence determine the domain of f(x) ,find the range of f(x) , find an expression for f(3x+1) and hence determine f(4)

SuperNover:
boss! thanks a million fold. I appreciate. I really do.

SuperNover:
help me out anyone in the house.

if f(y-4)=y²+2y+3, then find f(2)

[b]Guys that have been mentioning me, abeg dont add salt upon my injuries. What happened was very painful. I'm slowly recovering so do me jejely bikonu.

Manu Garba and Nduka Ugbade are rogues. They ought to be banned from ever going near our national teams again.

You see, it's not the defeat that is the problem, it's the manner of the defeat. After the defeat, I made a few calls to Nigeria journalists that are there with them in New Zealand and the revelations were startling. The man we taught was an upright man is actually a shenanigan. I'm more than disappointed.

The following tweets are by the guy who was supplying us with the team lineup and inner news of camp and team happenings. He is alos highly respected by @guysly2much whom a couple of people here get their inside sources from. Look at what he has to say

All tweets by https://twitter.com/MuyiwaLawal . You can check his timeline to confirm for yourself.


















Well, I guess it's time to move on. Hopefully, the boys succeed on an individual level.

Those that are saying we've deserted the thread, you are merely sour losers, trying to gloat in your prediction that the team is overrated. There is nothing overrated in this team. I stand convinced that no team can stand the firepower in this team save for the filthy lucre of the coach.

I still stand by the boys, not the team managed by those fraudsters.[/b]

Good solution, naturalwaves. But I don't think you can mathematically cancel "!" signs like that. It's just sufficient to say (6-x)=4, I believe.

thanks .if you don't mind can u pls help with the explanation to this

3. Prove that the equation mx(x2 + 2x + 3) = x2 – 2x – 3 has exactly one real root if m = 1 and exactly 3 real roots if m= -2/3



For this question, you can use Descartes's rule of signs. You should actually use the more detailed Sturm's extension of this rule, but i think the former could be okay here.
Descartes's rule of signs says if v is the variation of sign in a polynomial p(x) and the number of positive real zeros (roots) is n, then
n<=v and v-n is even.

Same applies to number of negative real zeros with p(-x)

With m=1, you get
x3 + x2 + 5x + 3 = 0

p(x) = x3 + x2 + 5x + 3
No sign variation, so v=0.
n will also be 0 so there are no positive real roots.

p(-x) = -x3 + x2 - 5x + 3

Number of sign variation is 3 (- to + to - to +)
n will be 1, so that 3-1 is even. So there's a negative real root.

Equation thus has one negative real root and two complex roots which will be conjugates.


With m= -2/3

p(x) = -(2/3)x3 - (7/3)x2 + 3

Number of sign variation is 1. n will be 1 so that 1-1=0 which is even.
Hence, one positive real root.

p(-x) = (2/3)x3 - (7/3)x2 + 3.

Number of sign variation here is 2. n cannot be 1, cos v-n should be even. So n is 2. And 2-2=0.
So we have two negative real roots.

Hence, three real roots (one positive and two negative)

please boss check the division ,i have been trying to follow up the solution but couldn't come up with same answer as ur's don't knw if i'm doing the wrong thing

i want to say a very big thank your to all of those gurus who helped me in solving the maths problem i pasted, i appreciate all of you with a million thanks. pls i still need you help on this other question>


1. let a function f be defined by
f(x)=x²-2x-3/x²+2x+3
a. determine the domain of f(x)
b. find the range of f(x)
