Question

100 pts Given f(x) = x2 − 6x + 1, what is the domain of f(x)?

x ≥ 1
x ≤ −3
x ≥ −6
All real numbers

Answer 1

All real numbers

Explanation:

Answer 2

All real numbers

Explanation:

domain of a quadratic equation is all real numbers (if constraints are not there).

`f(x) = x^2 -6x + 1`

in above equation,

`\text{for x in } (-\infty, \infty)` there exist a unique value of y for each x, hence the domain is all real numbers.

(range of the above function is
`[-8, \infty)`)
