Given:
The graph of function.
To find:
The correct statement for the domain and range of the given graph.
Solution:
Domain: The set of input values.
Range: The set of output value.
From the given graph it is clear that the graph represents a polynomial function.
The given graph of a polynomial function is defined for all real values of x. So, the domain is the set of all real numbers.
The graph of the function approaches from negative infinite to positive infinite. So, the output the given graph is set of all real numbers. It means the range is the set of all real numbers.
Therefore, the correct options are B and D.
Answer:
4
Step-by-step explanation:
Since it costs $3.75 for every earring, multiply e by 3.75 like this: 3.75e
Add 9.5 on top of that since Dani already bought the necklace for $9.50
3.75e + 9.5
This sum has to be less than or equal to 25 because the budget is $25
3.75e + 9.5 ≤ 25
To find e subtract 9.5 from both sides
3.75e + 9.5 ≤ 25
- 9.5 - 9.5
3.75e ≤ 15.5
Divide both sides by 3.75
3.75e/3.75 = 15.5/3.75 = 4.133...
You can't buy 0.133 of an earring, so the max amount of earrings she can buy is 4.
For roots r1 and r2, the factors are (x-r1)(x-r2)
r1=i
r2=-i
don't forget i^2=-1
(x-i)(x-(-i))=(x-i)(x+i)=x^2-i^2=x^2-(-1)=x^2+1
the function is
f(x)=x^2+1
Thanks for the correction. Answer: No,
is a polynomial expression because it has a break between numerical exponents. It goes from
to
, which makes it in the form of
to
which means that it is NOT a polynomial.
