Answer:
- D. It is a many-to-one function
Step-by-step explanation:
- One-t<em>o-one if every y value has exactly one x value mapped onto it</em>
- <em>Many-to-one if there are y values that have more than one x value mapped onto them.</em>
We have a function that is of degree 3, so it has 3 x-intercepts which means there are points (x₁, 0), (x₂, 0), (x₃, 0), so it is a many-to-one function
Correct option is D
Answer:
Step-by-step explanation:
Things to remember:
1). When we divide a number having decimal by 10, 100, 1000 or any number multiple of ten, decimal point of the numerator shifts left by the number of zeros present in denominator.
Example:
2). When we multiply a decimal number by 10, 100, or any number number multiple of 10, decimal point of the original number shifts right by number of zeros present in multiplier.
Example: 2.0 × 100 = 200
In this question, 0.014 × 100000 = 1400.000
Therefore, product of 0.014 and 100000 is 1400 because the decimal point in 0.014 moves 5 places to the right.
