Q

FIND HOW TO FIND DERIVATIVE OF GRAPH

For example f’(2)

A

Use slope

Find slope on graph at f(2)
Then find derivative if while function(use rules)
Then plug in value if x which is 2 into f(x) and value of g’(x) which si the slope for f’(x)

Q

find all t for which the particle is moving right

A

find derivative of position function to find velocity

solve for t

turn the solutions into intervals

ex. t= 0, t= 3

interval [0,3) (3,infinity)

then choose a pt in interval and plug into v(t)
see if positive or negative (positive means moving it the right)

Q

find all t for which speed of particle is increasing justify

check if v(t) and a(t) are same sign

A

plug in number for v(t) and for a(t) if some sign then the particle is increasing
