Step-by-step explanation:
Multiply straight across (neg times a neg = a positive)
=28/81
Answer:
Step-by-step explanation:
A = -2.2
E.
( -2.1 ) + ( - 0.1 )
( -2.1 ) - 0.1. <—— over there, you will see that + is gone and the - has moved down, I done that because + plus with - equals to -.
-2.1
-0.1
———-
-2.2
Answer:

Step-by-step explanation:
Next time you should write the correct form of equation
because it affects greatly the answer. I believe the correct form would be:
f (x) = 2 * x^2 + 1
where the second 2 is a power of x
The average rate of change is also defined as the slope
of the equation. Therefore:
average rate of change = slope
Where slope is:
m = (y2 – y1) / (x2 – x1) = [f (0) – f (-1)] / (x2 – x1)
Calculating for f (0): x2 = 0
f (0) = 2 * 0^2 + 1 = 1
Calculating for f (-1): x1 = -1
f (-1) = 2 * (-1)^2 + 1 = 3
Substituting the known values to the slope equation:
average rate of change = (1 – 3) / (0 – 1)
average rate of change = -2 / -1
average rate of change = 2
