Q: The slope of the line tangent to the graph of y=f(x) at the input value x=5 is shown in the graph below. What does it mean to say that the slope of this tangent line is 0.712?
- The value of f(x) changes by 0.172
- The value of f(x) changes by 0.172 times 5
- The value of f(x) changes by 0.172 divided by 5
- The value of f(x) changes by 0.172 times dx
- The value of f(x) changes by 0.172 divided by dx
A: The value of f(x) changes by 0.172 times dx
