Answer:

All real numbers

Step-by-step explanation:

The domain represents the x-coordinates, so you can see on the graph that it goes all the way out to both the left and right directions, meaning it covers all the negative numbers, and all the positive numbers. The question is trying to trick you into thinking about the range, but forget about the y-axis for this one.

Anna is swimming against the ocean current. The following equation models her speed: f(x) = x2 − 6x +1, where x is Anna's speed

REY [17]

Answer:

All real numbers

Step-by-step explanation:

we have the function

$f(x)=x^2-6x+1$

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

(B)
if <em>f</em>(a) = K, then that means <em>f </em>sends (a) to (K).
the inverse function, <em>f</em>-1, goes back where you started, so <em>f</em>-1 <em />sends (K) to (a).
<em>f</em>-1(K) = a.
