Step-by-step Solution

Para encontrar la pendiente de la recta secante que interseca la gráfica de \( h(x) = 16 - x^2 \) en los puntos \( x = 1 \) y \( x = 4 \), primero necesitamos calcular los valores de \( h(1) \) y \( h(4) \). 1. Calculamos \( h(1) \): \[ h(1) = 16 - (1)^2 = 16 - 1 = 15 \] 2. Calculamos \( h(4) \): \[ h(4) = 16 - (4)^2 = 16 - 16 = 0 \] Ahora tenemos los puntos de intersección: - En \( x = 1 \), el punto es \( (1, 15) \). - En \( x = 4 \), el punto es \( (4, 0) \). La fórmula para la pendiente \( m \) de la recta secante que pasa por los puntos \( (x_1, y_1) \) y \( (x_2, y_2) \) es: \[ m = \frac{y_2 - y_1}{x_2 - x_1} \] Sustituyendo los valores de nuestros puntos: - \( (x_1, y_1) = (1, 15) \) - \( (x_2, y_2) = (4, 0) \) Sustituyendo en la fórmula: \[ m = \frac{0 - 15}{4 - 1} = \frac{-15}{3} = -5 \] Por lo tanto, la pendiente de la recta secante es \( \boxed{-5} \).

Quick Answer

La pendiente de la recta secante es -5.
