Because you are shifting the function to the left by 2 units, you will represent that as:

Because you are shifting the function to the left by 2 units, you will represent that as:
$f(x) = (x+2)^2-7$

Generally, if you are moving to the left, it's seen going in the negative direction, but remember since f(x) is going to the left, it means that you are solving for x. So, solve for x in (x + 2), you get x = -2. Hopefully this makes sense.

The, you are dilating the entire function in which you have to multiply the entire thing. Let's do it:
$f(x) = 3((x+2)^2-7)$

Which is equal to:
$f(x) = 3(x+2)^2 -21$

So, your answer is D. If anything doesn't make sense to you, please tell me, I'd be happy to explain!

Find the center and radius of the circle with equation (x + 3)^2 + (y – 6)^2 = 100.

Sonja [21]

Answer:

center (-3,6)

radius(r) 10

Step-by-step explanation:

The center-radius form (it is really called standard form) of a circle is:

$(x-h)^2+(y-k)^2=r^2$

where $(h,k)$ is the center and $r$ is the radius.

Compare the following:

$(x-h)^2+(y-k)^2=r^2$

$(x+3)^2+(y-6)^2=100$

You should see the following:

$-h=3$

$-k=-6$

$r^2=100$ .

$-h=3 \text{ implies }h=-3$ .

$-k=-6 \text{ implies } k=6$ .

$r^2=100 \text{ implies } r=\sqrt{100}=10$ .

So the center is (-3,6) and the radius is 10.

Mr. Jones is taking his family to see a play. There are 10 people going to the play, and they

$13.10. This is because you multiply $5.50 x 2 due to the amount of cars which leaves you off with $11 total. Then you take away $11 from the total price of $142 which leaves you off with $131.00 from there you divide the amount of people going which is 10. So you’ll get 131/10 = $13.10
