y = f(x) ( - 2) (- 1/4) (4 1/2) (√2 + 2)
y = g(x) (- 1 1/4) (1/2) (5 1/4 ) (√2 + 2 3/4)
y = h(x) (- 5 ) (- 3 1/4 ) [√(2 1/4)] (√2- 1 )
Dane do tabelki
1.
f(x) = - 2
g(x) = f(x) + 3/4 = - 2 + 3/4 = - 1 4/4 + 3/4 = - 1 1/4
h(x) = f(x) - 3 = - 2 - 3 = - 5
2.
g(x) = 1/2
g(x) = f(x) + 3/4
1/2 - 3/4 = f(x)
f(x) = 2/4 - 3/4 = - 1/4
h(x) = f(x) - 3 = - 1/4 - 3 = - 31/4
3.
h(x) = f(x) - 3
√(2 1/4) = f(x) - 3
√(9/4) = f(x) - 3
3/2 = f(x) - 3
f(x) = 3/2 + 3 = 3 3/2 = 4 1/2
g(x) = f(x) + 3/4 = 4 1/2 + 3/4 = 4 2/4 + 3/4 = 4 5/4 = 5 1/4
4.
f(x) = √2 + 2
g(x) = f(x) + 3/4 = √2 + 2 + 3/4 = √2 + 2 3/4
h(x) = f(x) - 3 = √2 + 2 - 3 = √2 - 1
