Question

f(x) = x^2 - 7x + 8

the domain of f(x) is
(type your answer in interval notation.)

Explanation:

Identify the function type

$$ f(x) = x^2 - 7x + 8 $$

Determine the domain restrictions

$$ \text{No division by zero, no negative values under square roots.} $$

Write the domain in interval notation

$$ (-\infty, \infty) $$

Answer:

The domain of \(f(x)\) is <blank>\((-\infty, \infty)\)</blank>
