the graph of f(x) is shown below. estimate and list the value(s) of x where f(x) has a horizontal tangent. note: this is the same as finding the x-values where the slope of the tangent line is 0.
Answer
Explanation:
Step1: Recall tangent - slope relationship
A horizontal tangent has slope 0. We look for points on the graph where the curve has a flat appearance.
Step2: Identify flat - looking points on the graph
From the graph, we can see that the function $f(x)$ has a flat appearance (horizontal tangent) at approximately $x=-6$ and $x = 6$.
Answer:
$x=-6,6$
