Answer:
The V-shaped graph opens downward, and its vertex lies at (1, 12).
Step-by-step explanation:
- first, plot the graph of f(x),
- take some 5 random negative and positive x values and then find corresponding f[x] values.plot f(x) on y-axis. now, plot these points on the graph and finally join all the points. this gives u the required graph.
- I have plotted the graph and uploaded it.
refer it.
- by seeing the graph, we can easily say that,The V-shaped graph opens downward, and its vertex lies at (1, 12).
We will use l´Hopital´s rule for calculating limits involving indeterminate form (in this case: ∞ / ∞ ) using the derivative of the numerator and denominator:

This is still form ∞/∞ and we will use the derivative again:

=1/∞ =
0The sequence converges.
Answer:
8x-1
Step-by-step explanation:
add up all the x's which will be 8x
then do the regular numbers which is -2+1 is -1
therfore it is 8x-1
Answer:
If you're looking for a shortcut, I usually find the number 1 less than what you are multiplying 9 by, this case 8, and then add a number that gets to 9.
So 9x6 would be:
5+4=9
54
Step-by-step explanation:
When multiplying by 9s the product's two numbers added together =9.
Sorry if this is confusing. Hope this helps though.
