you add them together to get 8/8 and that simplifies to 1
To find the average rate of change of given function f(x) on a given interval (a,b):
Find f(b)-f(a), b-a, and then divide your result for f(b)-f(a) by your result for b-a:
f(b) - f(a)
------------
b-a
Here your function is f(x) = x^2 - 2x + 3. Substituting b=5 and a=-2,
f(5) = 5^2 -2(5)+3 =? and f(-2) = (-2)^2 - 2(-2) + 3 = ?
Calculate f(5) - [ f(-2) ]
------------------ using your results, above.
5 - [-2]
Your answer to this, if done correctly, is the "average rate of change of the function f(x) = x^2+2x+3 on the interval [-2,5]."
Answer:
3 hundredths.
Step-by-step explanation:
After the decimal point the unit becomes tenths, hundredths, thousandths and so on. The 3 is in the hundredths column.
Answer:
68
Step-by-step explanation:
m7 + m8 = Straight line = 180
So, m7 = 180 - 112 = 68
Here is the graph with your line in it.
