1. Oblicz miejsce zerowe funkcji:
zał. y=0
a y=2x -1
b) y=6x+5
c) y=5
d) y= -1/4x + 8
e) y=0,5x -1
f) y=-3x + 2/3
a)
y= 2x - 1
2x - 1 = 0
2x = 1 /:2
x = 0,5
b)
y = 6x + 5
6x + 5 = 0
6x = - 5/:6
x = -5/6
c)
y = 5
Brak miejsc zerowych
d)
y = -1/4x + 8
-1/4x + 8 = 0
1/4x = 8 /*4
x = 32
e)
y = 0,5x - 1
0,5x - 1 = 0
0,5x = 1 /*2
x = 2
f)
y = - 3x + 2/3
- 3x + 2/3 = 0
3x = 2/3 /:3
x = 2/9
