Answer:

Step-by-step explanation:
step 1
we have the points
(-1,0), (-2,0), and (0,2)
Plot the points
using a graphing tool
see the attached figure
The graph of a quadratic function must be a vertical parabola open upward
The vertex is a minimum
The quadratic function in general form is equal to

Substitute the value of x and the value of y of each given ordered pair in the general equation and solve for a,b and c
(0,2)
For x=0, y=2
substitute

(-1,0)
For x=-1, y=0
substitute

---->
----> equation A
(-2,0)
For x=-2, y=0
substitute

----> equation B
we have the system
----> equation A
----> equation B
substitute equation A in equation B
solve for b

Find the value of a
therefore
The quadratic function in general form is equal to

see the attached figure N 2 to better understand the problem
Answer:
I cant solve number 1 but I can for number 2
Calculate GCF for each
You can learn how to use the prime factorization method to do this
GCF(12, 18, 40, 45) = 1
So I dont get what the problem is because there are no numbers for #2. So either I dont understand the problem or it is a trick question whereas the answer is UNDEFINED/IMPOSSIBLE.
I will try my best to assist you with your question!
3/25 = .12 or 12%
12% can also be written as .12
3/25% in decimal form is .12
Hope I helped!
Good Luck!
Answer:

Step-by-step explanation:
We are asked to find
of function
using definition of derivatives.
Limit definition of derivatives:

Let us find
and
.




Substituting these values in limit definition of derivatives, we will get:


Make a common denominator:





Cancel out h:




Therefore,
.
