2 / 2 pts Question 7 The graphs of two functions $f(x)$ and $g(x)$ are shown below. These two functions have the following property: For any value of $x$, the line tangent to the graph of $f$ at the point $(x,f(x))$ has the same slope as the line tangent to the graph of $g$ at the point $(x,g(x))$. The figure demonstrates this for $x=1$ as an example. Which of the following statements is true? The functions and are equal. Correct! Correct!
