1. Evaluate the piecewise function for the given value of x. f(x) =
(2x, x>4
22 0 < x < 4
-7, x < 0
f(4) =?
O A. -7
OB. 8
C. 16
D. 4

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

step-by-step explanation:

ik this stuph and i am smart donkey

i cant answer this, theres no table. sorry man

step-by-step explanation:

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
