What is the domain of f?

SOMEONE PLEASE HELP

Finding the Domain of a Function Using a Natural Log Write the problem. Let's say you're working with this one: f(x) = ln(x-8) Set the terms inside the parentheses to greater than zero. The natural log has to be a positive number, so set the terms inside the parentheses to greater than zero to make it so. Solve.

Step-by-step explanation:

First what is domain of f/function?

A domain is part of a function f if f is defined as a triple (X, Y, G), where X is called the domain of f, Y its codomain, and G its graph. A domain is not part of a function f if f is defined as just a graph.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

d. all of the above
