what key features can be identified from graphs of polynomials with higher degrees and explain how the key features can be used

Natali [406]

Polynomials are algebraic expressions that contain more than two terms. AN example would be: f(x) = x^3 + x^2 + x +1. This equation contains three terms, with the 3rd degree as its highest term. It also means that the graph passed three x-intercepts. This depends in the highest degree. So, the first thing you do is plot the intercepts because for sure, the graph will pass there.

Find the derivative using the limit process of f (x) = - 10x

zubka84 [21]

Answer:

$\frac{d}{dx} f(x) =-10$

General Formulas and Concepts:

Calculus

Derivative Notation
Definition of a Derivative: $\lim_{h \to 0} \frac{f(x+h)-f(x)}{h}$

Step-by-step explanation:

Step 1: Define

f(x) = -10x

Step 2: Find Derivative

Substitute: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10(x + h)-(-10x)}{h}$
Distribute -10: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10x -10h-(-10x)}{h}$
Distribute -1: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10x -10h+10x}{h}$
Combine like terms: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10h}{h}$
Divide: $\frac{d}{dx} f(x)= \lim_{h \to 0} -10$
Evaluate: $\frac{d}{dx} f(x)=-10$

Find the missing length of the triangle.

Dafna1 [17]

There are special properties to certain right triangles.

A 3-4-5 triangle will always be a right triangle. 9 divides into 3, and 15 divides into 5, so you can use ratios to find b.

Since 9 divides into 3, we will use this to set up proportions for the missing value:

$\frac{9}{3} = \frac{b}{4}$

Cross multiply the fractions.

$3b = 36$

Divide both sides by 3.

$b = 12$

The missing value is 12.
