The answer is 12 because you divide 204 by 17 to get what x is

Which function below would have the smallest Average rate of change From X =0 to x=2

babymother [125]

Answer:

See answer below

Step-by-step explanation:

Hi there,

To get started, recall the average rate of change formula (essentially the same thing as slope):

$Rate_{avg} = \frac{f(b)-f(a)}{b-a}$

So, just determine the average rate for each function between points [0,2] (a and b for the formula above, respectively).

To make it less time consuming, you do not need to do the division portion as it is same for all of them and (2-0) is greater than 1:

$f(2)-f(0)= \frac{1}{4} (2^{2} -0^{2} ) = 1 \\g(2)-g(0)= 5(2-0)= 10\\h(2)-h(0)= 2^{2} - 0^{2} =4$

Without even doing the divison of (b-a), we can already see that the function with smallest average rate of change between [0,2] is f(x).

thanks,

lbvjy [14]

First calculate the sum or difference: 8+(8+9)-19 x 5.
Second calculate the product or quotient: 8+17-19 x 5
Third calculate the sum: 8+17-95
Lastly subtract 25 - 95.

Then your answer is -70. Please give brainliest!

Please help me 20 points, has to be valid, if not you will be reported

Mila [183]

When x = 3, the value of y is y = 4 (row 3 of the table)
when x = 5, the value of y is y = -2 (row 4 of the table)

So we have the two points (3,4) and (5,-2)

To find the average rate of change from x = 3 to x = 5, this is the same as finding the slope of the line through (3,4) and (5,-2)

Slope Formula:
m = (y2 - y1)/(x2 - x1)
m = (-2-4)/(5-3)
m = (-6)/(2)
m = -3

The slope is -3 so the average rate of change is -3

The answer is choice B
