Sabemos que el límite elástico de un resorte es de ( 8 cm. ) y que la fuerza que se ejerce sobre él, es directamente proporcional a su estiramiento ( Ley de Hooke: F = K • X ) a la razón de ( 2 N/cm ). Determinar el Dominio de la función y su Rango. ( El rango de la función es el subconjunto del contradominio que está relacionado con el dominio ), ( F = ( 2 N/cm.) X ) a)Dominio = ( X / 0 ≤ X ≤ 8 ) Rango = ( Y / 0 ≤ Y ≤ 16 )

b)Dominio = ( X / 1 ≤ X ≤ 7 ) Rango = ( Y / 2 ≤ Y ≤ 18 )

c)Dominio = ( X / 2 ≤ X ≤ 8 ) Rango = ( Y / 0 ≤ Y ≤ 24 )

d)Dominio = ( X / 0 ≤ X ≤ 9 ) Rango = ( Y / 0 ≤ Y ≤ 16 )

step-by-step explanation:

i just used a calculator

a 360 degree rotation

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
