For the graphed function f(x) = (2)x + 2 + 1, calculate the average rate of change from x = −1 to x = 0. graph of f of x equals
Leni [432]

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

-1/4×3/5×-2/5 what dose this Equal
Alex787 [66]

Answer:

3/50

Step-by-step explanation:

Multiply across the fraction- First start with the numerator digits (-1, 3, and -2)

-2*-1= 2 and 2*3= 6 So you should have 6 as your numerator

Now look at the denominator digits (4, 5, and 5)

Multiply across and you should get 100 as your denominator

You now have 6/100 but you are not done yet! Don't forget to simplify the fraction to get your final answer

Both 6 and 100 are divisible by 2 (6 divided by two is 3, and 100 divided by two is 50)

Thus, your final answer should be 3/50!
