Answer:

-x^2 + 4

Step-by-step explanation:

Multiply; (2 + x)(2 - x)

= 4 - 2x + 2x - x^2

Combine Like Terms; 4 (-2x + 2x) -x^2

= 4 - x^2

Put in Final Form;

= -x^2 + 4

If you need to solve for X;

Subtract 4

-4 = -x^2

Divide both sides by -1;

4 = x^2

Square root both sides;

2 = x

The function y = f(x) is graphed below. What is the average rate of change of the
Serjik [45]

The average rate of change of the function in the given interval -3 ≤ x ≤-1 is 10.

<h3>What is the average rate of change?</h3>

The average Rate of Change of the function f(x) can be calculated as;

f(x) = \dfrac{f(b) - f(a)}{b-a}

Interval -3 ≤ x ≤-1

a = -3, b = -1

f(a) = f(-3) = -20

f(b) = f(-1) = 0

Step 2: Find Average

f(x) = \dfrac{f(b) - f(a)}{b-a}\\\\\\f(x) = \dfrac{f(-1) - f(-3)}{-1-(-3)}\\\\\\f(x) = \dfrac{0 - (-20)}{2}\\\\f(x) = 10

Therefore, the average rate of change of the function in the given interval -3 ≤ x ≤-1 is 10.

For questions 1- 3 find the exact sum or difference.
7nadin3 [17]
D, Because 7/15 + 9/15 is 16/15 + 4/15 =20/15 which equals 1 5/15 which turns into 1 1/3
A, 1/21 + 2/21 = 3/21 and that equals 1/7

C, 3/14+3/12 turns into 3/14+5/14= 10/14 - 8/14= 2/14=1/7

A function P(x) has both 2 and 3 as roots, x=5 is a solution such that P(5)=0, and the degree of P(x) is 2. Explain why no such
antiseptic1488 [7]

Answer:

Step-by-step explanation:

Roots mean the the function has a result of zero at that point. This function would therefore have zeros at 2, 3 and 5 and the degree would be at LEAST 3 and possibly higher depending on the multiplicity of each root.

factors would be

(x - 2)ⁿ¹(x - 3)ⁿ²(x - 5)ⁿ³    where n₁, n₂ and n₃ are Whole numbers ≥ 1
