Determine the domain and range for the function m(x)=-x^2+4x-3

domain is all real numbers

range is y is less than or equal to 1 (it is a downward parabola)

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

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.
