Question

What’s the answer to this radical function

Answer 1

Explanation:

We have,

`f(x) = - 2 \sqrt[3]{x + 7}`

Taking limit,

`\lim _(x \rarr \infty ) f(x) \\ = \lim _(x \rarr \infty ) - 2 \sqrt[3]{x + 7}`

If x approaches to positive infinity,

this implies f(x) approaches to negative infinity
