1. 13

2. 13

3. 12

4. 9

5. 1

A. y = -3.07x^2 +0.41x + 15.65

B. y=19.61(0.69^2)

c. y= -2.34x^2 + 2.19x + 16.25

D. y = -1.11x^2 + 3.74x + 10.64

Answer: The person who said it's D is right

Step-by-step explanation: I took the test and I got it right

The quadratic **regression equation** that fits these data is -1.107 X² +3.736 X +10.643 .

A **quadratic regression **is the process of finding the **equation **of the parabola that best fits a set of data. As a result, we get an **equation **of the form:

y=ax2+bx+c where a≠0 .

The best way to find this equation manually is by using the least squares method.

That is, we need to find the values of a ,b, and c such that the squared vertical distance between each point (xi,yi) and the **quadratic curve **y=ax2+bx+c is minimal.

After solving we get the values of a , b, and c and thus we form the equation

-1.107 X² +3.736 X +10.643

f(x) = 3x2 – 2x - 9

g(x) = 3x2 + 2x2 - 4x - 9

Find (f - g)(x).

9514 1404 393

**Answer:**

(f -g)(x) = -3x^3 +x^2 +2x

**Step-by-step explanation:**

We assume the expression for g(x) has a typo, and the first term should be 3x^3.

(f -g)(x) = f(x) -g(x) = (3x^2 -2x -9) -(3x^3 +2x^2 -4x -9)

= 3x^2 -2x -9 -3x^3 -2x^2 +4x +9

= -3x^3 +(3 -2)x^2 +(-2+4)x +(-9+9)

**(f -g)(x) = -3x^3 +x^2 +2x**

Maggie bought c CDs for $12 each, b books for $7 each, and a purse costing $24.

a. Write an expression to show the total amount of money Maggie spent.

b. If Maggie bought 4 CDs and 3 books, how much money did she spend?

**Step-by-step explanation:**

Given that,

Maggie bought c CDs for $12 each, b books for $7 each, and a purse costing $24.

(a) Cost of c CDs = 12c

Cost of b books = 7b

Cost of p purse = 24p

Total amount = 12c+7b+24p

(b) Cost of 4 CDs = 12(4) = $48

Cost of 3 books = 7(3) = $21

Hence, this is the required solution.

What is the inverse of the function y = 2x + 3?

**Answer:**

y = x/2 - 3/2

**Step-by-step explanation:**

**Answer:**

y = x/2 - 3/2

**Step-by-step explanation:**

First, get x on its own:

Subtract 3 from each side

y - 3 = 2x

Divide through by 2

y/2 - 3/2 = x

or x = y/2 - 3/2

Now simply switch labels: x↔y

y = x/2 - 3/2
