Odpowiedź:
a ) f ( x) = 7*( x + [tex]\frac{3}{4}[/tex] ) = 7 x + [tex]\frac{21}{4}[/tex]
a = 7
=====
Dla x = 0 mamy y = f ( 0 ) = 7*0 + [tex]\frac{21}{4} = 5 \frac{1}{4}[/tex]
P = ( 0 , 5 [tex]\frac{1}{4}[/tex] )
============
b ) g ( x) = [tex]\frac{6 - 5 x}{4} = \frac{6}{4} - \frac{5}{4}[/tex] x = - [tex]\frac{5}{4}[/tex] x + [tex]\frac{3}{2}[/tex]
a = - [tex]\frac{5}{4}[/tex]
Dla x = 0 mamy y = g ( 0 ) = - [tex]\frac{5}{4} *0 + \frac{3}{2} = \frac{3}{2} = 1,5[/tex]
B = ( 0 , [tex]\frac{3}{2}[/tex] ) = ( 0 ; 1,5 )
