- Dada f(x) = 3 – 4x, calcule f (a), f (a + 1) y f(a) + f(1)
f(a) = 3 – 4(a) = -4 a + 3
f(a + 1) = 3 – 4(a + 1) = 3 – 4a – 4 = - 4a – 1
f(a) + f(1) = 3 – 4(a) + (1) + 3 – 4(1) = 3 – 4a + 1 + 3 – 4 = 3 + 3 – 4 – 4a = -4a + 2
- Dada f(x) = , calcule f(3), f(-2), f(a), f( y f(x + h)[pic 7][pic 8]
f(3) = = 9[pic 9]
f(-2) = = 4[pic 10]
f(a) = = [pic 11][pic 12]
f( = = x[pic 13][pic 14]
f(x + h) = = = + 2xh + = [pic 15][pic 16][pic 17]
- Dada f(x) = 3 + 7, calcule f(c), f(c + h) y f (c + h) – f(c)[pic 18]
f(c) = 3( + 7 = 3( + 7 = 3 + 7[pic 19][pic 20][pic 21]
f(c + h) = 3( + 7 = 3(+ 7 = 3 + 6ch + 3 + 7[pic 22][pic 23][pic 24][pic 25]
f(c + h) – f(c) = 3 ( - 3( + 7 = 3(- 3 + 7[pic 26][pic 27][pic 28][pic 29]
= 3 + 3ch + 3 – 3 + 7[pic 30][pic 31][pic 32]
= 3ch + 3[pic 33]
- Dada f(x) = 3, calcule f(1 / x), f(, f(x + 2) y f(x + h)[pic 34]
f(1 / x) = 1/3
f() = ) = 3 x 3 = 9[pic 35][pic 36]
f(x + 2) = (3) + 2 = 3 + 2 = 5
f(x + h) = (3 + h) = 3 + h
- Dada f(y) = 5, calcule f(1 / y), f( f(y + 3), f(7) y f(y + h)[pic 37]
f(1/y) = 1/5
f( = = 5 x 5 = 25[pic 38][pic 39]
f(x + 3) = (5 + 3) = 5 + 3 = 8
f(7) = 5
f(y + h) = 5 + h
- Dada f(x) = calcule f(4), f( y f()[pic 40][pic 41][pic 42]
f(4) = [pic 43]
f( = [pic 44][pic 45]
f(= = a + h[pic 46][pic 47]
- Dada f(x) = -4 [pic 48][pic 49][pic 50]
f(25) = = = 5 – 4 = 1[pic 51][pic 52]
f(0) = 0 – 4 = -4[pic 53]
f(7) = -4[pic 54][pic 55][pic 56]
Conclusiones
Hemos podido concluir que este tipo de ecuaciones es muy importante, ya que podemos identificar perfectamente que es una ecuación, y mayormente enfocarnos en las ecuaciones lineales.
El propósito de dicha actividad será que los estudiantes sepan identificar perfectamente que es una ecuación, sistema de ecuaciones y sistema de ecuaciones lineale.
