Anna is swimming against the ocean current. The following equation models her speed: f(x) = x2 − 6x +1, where x is Anna's speed relative to land. What is the domain of the function?

x ≥ 1
x ≤ −3
x ≥ −6
All real numbers

All real numbers

Step-by-step explanation:

we have the function

This is a vertical parabola open upward

The vertex represent a minimum

Remember that

The domain of a function is the set of all possible values of x

The quadratic functions are continuous and defined for all real values of x.

therefore

The domain of the function f(x) is the interval (-∞,∞)

That means

All real numbers

All real numbers

Step-by-step explanation:

I took the test

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
