What is the domain of x^3 -2 +1
1 answer:
Answer:
All real numbers
Step-by-step explanation:
Assuming the polynomial is
Then the domain is all real numbers.
The domain are all values of x, for which the given function is defined.
The reason is that, polynomials are defined everywhere on the real number line.
We can write this as {x|x is all real numbers} .
Or (-∞,+∞)

Answer:
- The part (0, 12000) is constant and the slope is zero
- The part (12000, 38000) is decreasing and slope is negative 0.26.
Step-by-step explanation:
Checking the given graph, we see that
For x = 0 to x = 12,000, the values of y are unchanged. For this, we say it is constant.
The slope here is: 0.85 - 0.85 = 0
For x = 12,000 to x = 38,000, the values of y are decreasing. For this, we say it is negative.
The slope here is: 0.59 - 0.85 = -0.26.
