## Calculus (3rd Edition)

We have the equation: $f(x) \approx L(x)=f(a)+f^{\prime}(a)(x-a)$ We see that the Linear Approximation says that the vertical change in the graph is approximately equal to the vertical change in the tangent line. In other words, if we "zoom in" on any curve, it will approximately look like a straight line. Thus, the statement is true.
