Ok so, the "P" stands for parentheses, the "E" stands for exponents, orn^{n}. the "M" stands for multiplication, the "d" means you divide, the "a" means you add, and the "s" means you subtract. So, for question number 5, you would do  2x6 because there is no exponents or parentheses, so 2x6=12. Then you would add the 12 and the 4 together, so 12+4=16. Your answer is 16.

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
