Quick Answer

a. Área de triángulo: \( A = \frac{5h}{2} \) b. Volumen de cilindro: \( V = 7\pi r^2 \) c. Radio de círculo: \( r = \sqrt{\frac{A}{\pi}} \) d. Altura de triángulo: \( h = \frac{84}{b} \) a. \( f(x) = 2x^2 - 3x \): Parábola hacia arriba b. \( g(x) = 2x - 4 \): Línea recta c. \( h(x) = \sqrt{x + 3} + 3 \): Raíz cuadrada desplazada d. \( k(x) = x^3 - x^2 \): Función cúbica
