Question

Wyznacz miejsce zerowe funkcji. a) f (x) =x -6 b) f(x) = 2x+1 c) f(x) = 6x-3 d) f(x) = -8x+12 e) f(x) = -1/2x+5 f) f(x) = 0,01x-50

Answer 1

chyba tak ale pewności niemam -8x+12 iten znaczek

Answer 2

a)

f(x) = x-6

x-6 = 0

x = 6

b) f(x) = 2x+1

2x+1 = 0

2x = -1

x = -1/2

c)

f(x) = 6x-3

6x-3 = 0

x = 1/2

d)

f(x) = -8x+12

-8x = -12 |:-8

x = 2/3

e)

f(x)= -1/2x+5

-1/2x = -5 |*-2

x = 10

f)

f(x)=0,01x-50

0,01x = 50 |*100

x = 5000
