Example 1. Let us start with the functionf(x) = x2. We have

So

which means f '(a) = 2a.
What about the derivative of f(x) = xn. Similar calculations, using the binomial expansion for (x+y)n (Pascal's Triangle), yield

Answer:
<h2>
</h2>
Step-by-step explanation:
To find f(−1) , substitute the values of x that's - 1 into f(x). That is for every x in f(x) replace it with - 1
That's
We have the final answer as
Hope this helps you
Answer:
The answer is (3,2) or x=3 and y=2
Step-by-step explanation:
Answer:
B. 24
Step-by-step explanation:
Since both triangles are similar, therefore,
GM/XD = AG/KX
(x - 2)/6 = (x + 9)/9
Cross multiply
9(x - 2) = 6(x + 9)
9x - 18 = 6x + 54
Collect like terms
9x - 6x = 18 + 54
3x = 72
Divide both sides by 3
x = 72/3
x = 24
