Answer: 2x^2 + 7x + 2

Step-by-step explanation:

(3x^2 + 5) + (4x-2) - (x^2 - 3x + 1)

distribute the signs to the equations. subtraction on the last one is a little tricky because it turns all of the signs opposite. all subtraction in these kinds of problems is like this so you might want to watch out for this in the future. (:

distribute the signs to get:

3x^2 + 5 + 4x - 2 - x^2 + 3x - 1

simplify the equation. get all like variables together to get:

2x^2 + 7x + 2

Answer:

So Price after discount would be 17.5 on February 1st

Step-by-step explanation:

Given:

Original Cost  =57.75

Off Price = 70%

To Find:

Price after discount = ?

Solution:

We have to find the price after discount which is given by the formula

Price after Discount = Original Cost - Discount Price

We have to find the value of discount price

Discount Price = off Price * Original Cost

Putting in the values

Discount Price = 70 % * 57.75

it becomes

Discount Price =\frac{70*57.75}{100}

It becomes

                         =\frac{4025}{100}

                                = 40.25

Now

Price after Discount = Original Cost - Discount Price

Putting in the values

it becomes

Price after Discount = 57.75-40.25

                                   = 17.5

So Price after discount would be 17.5 on February 1st

Following changes are made in graph of G(x) to obtain F(x)

1) Vertical stretch by a factor of 2
So, G(x) will be changed to 2G(x)

2) Shift towards Right by 2 units
So, 2G(x) will be changed to 2G(x - 2)

3) Upward shift by 2 units.
So, 2G(x - 2) will be changed to 2G(x - 2) + 2

Thus,

F(x) = 2G(x - 2) + 2
F(x) = 2(x - 2)² + 2

Therefore, option C is the correct answer
