Ricardo lanzó una piedra desde un puente al río de abajo. La altura de la piedra (en metros sobre el agua), x segundos después de que Ricardo la lanza, está modelada por

w(x)=-5(x-8)(x+4)
¿Cuál es la altura máxima que alcanza la piedra?

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3

the answer is a reflection across the line m
