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

Mr. Pham wrote the equation below on the board.
Margaret [11]

Answer:

x=5.5

Step-by-step explanation:

We can solve this equation by using the various properties and PEMDAS.

First, we would want to subtract 18 on both sides, to even out the equation.

The result is -7x=-38.5

Now we can isolate the x by dividing both sides by -7.

-38/-7=5.5

Thus, x=5.5

Hope this helps!
