unit 2 test

Question 1

FIND HOW TO FIND DERIVATIVE OF GRAPH

For example f’(2)

Answer 1

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)

Question 2

velocity moves which directions

which positive which negative

Answer 2

left to right

left negative right post i’ve

Question 3

acceleration moves which directions

which positive which negative

Answer 3

up down

increasing decreasing

Question 4

the speed of a particle is increasing or accelerating if

Answer 4

the velocity and acceleration have the same sign

Question 5

what is speed

Answer 5

the absolute value of velocity

always positive

Question 6

find all t for which the particle is moving right

Answer 6

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)

Question 7

when to use brackets

Answer 7

if greater than ir equal to

AKA ENDPOINT

Question 8

always use parentheses for

Answer 8

infinity

Question 9

find all t for velocity increasing

means find the…

Answer 9

acceleration

do same as (find particle movin to right) velocity

Question 10

find all t for which speed of particle is increasing justify

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

Answer 10

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