Answer:
The polynomial is 
Leading coefficient is 1
Step-by-step explanation:
We need to determine the leading coefficient of polynomial p having roots
-1,1 and 2 and p(3)=24
Roots of polynomial are: -1,1,2
We can write them as:
x=-1, x=1, x=2
x+1=0, x-1=0, x-2=0
or:
(x+1)(x-1)(x-2)=0
Multiplying the terms to find the polynomial:

So, The polynomial is 
The leading coefficient is the coefficient with highest power So, in polynomial we have highest power
so, leading coefficient is 1
103^2-102^2
The property that applies here is a^2-b^2 = (a+b)(a-b)
so the answer is 103^2-102^2=(102+103)*(103-102)= numerically it is 205( as 103+102 = 205 and 103-102 = 1.....so 205*1 = 205)
The thing is that usually the factorization ends at (102+103)(102-103) ......
the answer is 7Г2÷2 (the first one)
To get the clear view about the domain and the range of the function, I have plotted the graph of the given function, it is showed in the attachment.
From the graph we can conclude that:
The domain is all real numbers. That is:
(-∞,∞)
The range is all positive real values. That is:
[0,∞)
b] Explanation:
As the values of x increases, the value of h(x) also increase.
Answer: A. $237.49
Step-by-step explanation:
First: Multiply 507 by 0.82 to see how many Euros he had when he started and you get 415.74
Next: Subtract 221 from 415.71 and you get 194.74
Then: Divide 194.74 by 0.82 and you get 237.487 which rounded would be A. $237.49
