Question

Функция вида f(х)=1/5х+5 аргумент=5;7;8;2,1;3,2

Answer 1

x=5
f(5) = 1/5 • 5 + 5 = 1 + 5 = 6

x= 7
f(7) = 1/5 • 7 + 5 = 7/5 + 5 = 6 2/5 или 6,4

x= 8
f(8) = 1/5 • 8 + 5 =8/5 + 5 = 6 3/5 или 6,6

x= 2,1
f(2,1) = 1/5 • 2,1 + 5 =1/5 • 21/10 +5 = 21/50 + 5 = 5 21/50

x= 3,2
f(3,2) = 1/5 • 3,2 + 5 = 1/5 • 32/10 + 5 = 32/50 + 5 = 5 32/50 = 5 16/25
