The average rate of change from x = -1 to x = 2 is 2
<u>Solution:</u>
Given function is:
f(x) = 2x - 1
We have to find the average rate of change from x = -1 to x = 2
<em><u>The average rate of change is given as:</u></em>
<em><u>The average rate of change from x = -1 to x = 2 is given by formula:</u></em>
<em><u>Find f(2) and f( - 1)</u></em>
<em><u>Substitute x = 2 in given function</u></em>
f(2) = 2(2) - 1 = 4 - 1 = 3
<em><u>Substitute x = -1 in given function</u></em>
f( - 1) = 2(-1) - 1 = -2 - 1 = -3
<em><u>Substitute the values in above formula,</u></em>
Thus average rate of change from x = -1 to x = 2 is 2

Answer:
8x + 80
Step-by-step explanation:
positive side
To solve this let us try to get x on it's own in the inequality.
-6<3x-12<=9
6<3x<=21
2<x<=7
Now a filled dot indicates <= or >= and empty indicates < or > so we know that the answer must have a filled dot on 7 and an empty dot on 2, with a line in between.
The answer is B, the selected one.
