Question

Which statement describes the end behavior of a function f x equals 3x - 7 - 7

Answer 1

Amanda, this is the solution to the exercise:

Step 1: Let's calculate the domain for the function given, as follows:

Domain of f(x) = 3 |x - 7| - 7 (-∞, ∞)

Step 2: Let's calculate the Lim of x, this way:

Limx 3 |x - 7| - 7 = ∞

In consequence, the end behavior is:

As x ==> +∞, f(x) ==> +∞

As x ==> -∞, f(x) ==> +∞

The correct answer is B. As x approaches negative infinity, f (x) approaches positive infinity.
