Answer:
If the function is , the domain are all values of x greater than or equal to -6
If the function is , the domain are all values of x greater than or equal to 1
Step-by-step explanation:
First case
we have
we know that
The radicand of the function must be greater than or equal to zero
so
the solution is the interval---------> [-6,∞)
therefore
The domain are all values of x greater than or equal to -6
Second case
we have
so
we know that
The radicand of the function must be greater than or equal to zero
so
the solution is the interval---------> [1,∞)
therefore
The domain are all values of x greater than or equal 1
Answer:
20/25
Step-by-step explanation:
its is another way to write it
Answer:
640 cm³
Step-by-step explanation:
V = 1/3Bh
So...
1/3(32)(60)
= 640 cm³
Answer:
It is B
Step-by-step explanation:
B:3=b
bx3=B
To find the zeros of the function
we need to factorize the expression.
a nice way to factorize
, if possible, is by completing the square as follows:
now we use the difference of squares formula
:
finally, we combine the results:
the zeros of f, are the values of x which make f(x)=0,
they are x=0, x=-2 and x=8
Answer: {-2, 0, 8}
