3-47.

Tables only give us select values of a function. What values are we given that are close to *t* = 6? Are these values close enough to find Marquita's exact velocity at *t* = 6?

Note: Since we do note know values that are infinitely close to *t* = 6, we can find Marquita's AROC (average velocity), not her IROC (actual velocity).

Use the Power Rule to find the IROC/derivative/slope function/velocity funciton.Then evaluate at *t* = 6 and again at *t* = 10.
