What is the domain and range for y=x3 – 4x² + x + 6
1 answer:
Answer:
Domain: set of Real numbers
Range{ set of Real numbers
Step-by-step explanation:
Since this is a cubic function, its domain and range are both the set of Real numbers.
The domain of any polynomial function is the set of Real numbers, And as far as the Range, we decide based on its end-behavior: since this is a polynomial with leading term , then it has the property of getting to infinitely large values for increasing values of x, and infinitely negative values for decreasing values of x.
