Sometimes I find it easier to let a calculator evaluate the function for me. The average rate of change is the change in output value divided by the change in input value. That is
.. average rate of change = (f(9) -f(2))/(9 -2)
For this function, this evaluates to
.. average rate of change = (25 -(-3))/(9 -2) = 28/7 = 4
_____
The graph shows the two points of interest connected by a line of slope 4, verifying our value for the average rate of change.
X2 + 6X +8
the answer is C. 4
Simplified would he 5x + 3
Answer:
C.
Step-by-step explanation:
Hope this helps! :)
Well a right triangle is made up of a 180 degree angle and take away 90 degrees because the right angle is already there so the answer is that PQR is a right triangle since the other two angles = 90 when added hope this helps i did alot of research:)
