Hello, everyone. Here in the studio with us is very promising young actor Billy
Banks. As you know he stars in recent Hollywood production “Money Talks”. I'm
Hi, everyone. I guess you've chosen me to talk about money because of my
Not only because of your name. I've known you for five years and I understand
you're a very rich man now. But in the film your character borrows money from
everyone to make his dreams come true. Have you ever borrowed money from

someone?
How much money do you earn?
Enough to live a comfortable life.
Do you try to save money or do you usually spend it as soon as you get it?
I've been saving money for
a flat in London but I can't afford to buy a good flat
yet. Though. I've already saved quite a lot - actually 80% of the money I need.
Have you ever lent money to someone who didn't pay you back?
Oh, lots of times. When I became famous, I found out that I had many friends
who wanted to borrow money from me. They've disappeared somewhere now. I've
been trying to get my money back, but - no luck.
We've chosen you for this interview because you're famous for spending your
money wisely - not on expensive cars or parties. You're also known as a person who
spends a lot on charity. How long have you been doing this?
I've been doing some work for charity since my drama school years. I've been
helping the poor children of Haiti for the last few years. And I'm proud to say that
we've already helped many children there. And if you want to help, you can visit my

f(x) = -2x² - x + 5 - квадратичная функция, график - парабола с ветвями, направленными вниз.

I x₀ = -b / (2a) = 1/(-2) = -0,5; y₀ = 5; B(-0,5; 5,25) - вершина параболы

Ось симметрии - прямая x = x₀, то есть в нашем x = -0,5;

Пункт 4) задания мы решили!

II В качестве точек для построения берем:

III Строим график (см. рисунок)

1) При x = -0,3; y ≈ 4,5; при x = 1,2; y ≈ 0,9; при x = 3; y = -16 (здесь проще подставить в функцию...)

2) y = 5 при x = 0 и при x = -0,5; y = 2 при x = 1 и при x = -1,5; y = -1 при x = -2 и при x = 1,5;

3) Нули функции (точки пересечения графика с осью OX)

При x₁ ≈ -1,9 или x₂ ≈ 1,4; y = 0;

Промежутки знакопостоянства:

При x ∈ (-∞; x₁) ∪ (x₂; +∞), f(x) < 0 (x ∈ (-∞; -1,9) ∪ (1,4; +∞))

При x ∈ (x₁; x₂), f(x) > 0 (x ∈ (-1,9; 1,4))
