Question

Find the domain of the function f(c) = -x^2 +8x +1 Use interval notation to express your answer. Preview

Answer 1

(-∞, ∞).

Explanation:

f(x) =
`-x^(2)+8x+1` is a polynomial function, so the domain is all real numbers (you can enter any value of x and i till return a valid y value). In interval notation is (-∞, ∞).
