The trail starts at the McCray Road parking area and runs for about 1 mile to a connection with a city of Cloverdale trail. The city trail runs 0.3 miles to the downtown area.
Intermediate Value Theorem. The Intermediate Value Theorem says that if a function is continuous and it's positive somewhere and negative somewhere else, then the function has to equal zero at some point between those two values. The important part of this theorem is to note that f(x) must be continuous.
The slope of the tangent line at 0 -- which would be the derivative at x = 0 -- therefore does not exist. (Definition 2.2 .). The absolute value function nevertheless is continuous at x = 0. For, the left-hand limit of the function itself as x approaches 0 is equal to the right-hand limit, namely 0.
