Question
![**Problem Statement:**
(20 points) Suppose that an object moves along the \( y \)-axis so that its location is \( y = x^2 + 8x \) at time \( x \). (Here \( y \) is in meters and \( x \) is in seconds.)
**Task:**
(A) Find the average velocity (the average rate of change of \( y \) with respect to \( x \)) for \( x \) changing from 3 to 8 seconds (include units [help (units)]).
Average velocity = [_________]
(B) Find the average velocity for \( x \) changing from 4 to \( 4 + h \) seconds.
Average velocity = [_________]
(C) Find the instantaneous velocity at \( x = 4 \) seconds (include units [help (units)]).
Instantaneous velocity = [_________]
**Instructions:**
- Calculate the average velocity over specified intervals.
- Determine the instantaneous velocity using appropriate calculus methods.
- Ensure that all answers include correct units for velocity.
