What is the average rate of change of the function f(x) = 4x – 2 over the interval x = –1 and x = 2?
Alexeev081 [22]

Answer:

4

Step-by-step explanation:

Given: f(x)=4x-2

To find:  average rate of change of the function f(x)=4x-2 over the interval x=-1 and x=2

Solution:

Take a=-1,\,b=2

Find f(a),\,f(b)

f(a)=f(-1)\\=4(-1)-2\\=-4-2\\=-6\\\\f(b)=f(2)\\=4(2)-2\\=8-2\\=6

Average rate of change of the function =\frac{f(b)-f(a)}{b-a}

=\frac{f(2)-f(-1)}{2-(-1)}\\\\=\frac{6-(-6)}{3} \\\\=\frac{12}{3}\\\\=4

The sum of a number w and 3 is less than or equal to ten.
Zinaida [17]
<h2>Answer:</h2>

In this problem we must translate English words into Algebraic Expressions. So we have the following English words:

<em>The sum of a number w and 3 is less than or equal to ten</em>

<em />

So let's do that using two steps:

<h3>1. The sum of a number w and 3:</h3>

Here we have two numbers w and 3. So we must makes the sum these numbers, therefore:

w+3

<h3>2. The sum of a number w and 3 is less than or equal to ten:</h3>

The symbol for the English words less than or equal to is ≤ hence we can write these words as:

\boxed{w+3\leq 10}

As you can see, the algebraic expression is an inequality.
