1- Dada a função f(x) = -3x + 5, determine:
a) f(0) b) f(-1) c) f(1) d) f(-2) e) f(2) f) f(-3) g) f(-3) h) f(-1/3) i) f(1/3) j) f(-5)
Soluções para a tarefa
f(x)= - 3x +5
f(0)= - 3.0+5= 0+5= 5
f(-1)= -3.(-1) +5= 3 +5= 8
f(1)= -3.1+5= -3+5= 2
f(-2)= -3.(-2) +5= 6+5=11
f(2)= -3.2 +5= -6+5= -1
f(-3)= -3.(-3) +5= 9+5= 14
f(3)= -3.3 +5= -9+5= -4
f(-1/3)= -3.(-1/3)+5= 3/3+5= 1+5= 6
f(1/3)= -3.(1/3)+5= -3/3+5= -1+5= 4
f(-5)= -3.(-5)+5= +15 +5= 20
Dada a função f(x) = -3x + 5, determine:
a) f(0) = -3.0+5= "5"
f(x) = -3x + 5
B) f(-1)= -3.(-1)+5=3+5="8"
f(x) = -3x + 5
c) f(1) = -3.1+5
f(1)= '-3+5'
F(1) = "2"
f(x) = -3x + 5
D) f(-2) = -3.(-2)+5=6+5=" 11"
e) f(2) = -3.2+5= -6+5= " -1"
_______________
f) f(-3)
f(x) = -3x + 5 = -3.(-3)+5=9+5="14"
G) f(3)
f(x) = -3x + 5
=-3.(3)+5= -9+5= '- 4'
____________________
f(x) = -3x + 5
h) f(-1/3) = -3.(-1/3)+5=1+5='6'
f(x) = -3x + 5
i) f(1/3) = -3.1/3+5= -1+5 = '4'
J) f(-5) =(-3) .(-5)+5=15+5= "20"
