Question

1) Sendo f(x) = 5x - 2, determine
a) f(1)=
b) f(-3)=
c) f(0)=
d) f(6)=
e) f(2/5) =
f) f(8)=​

Answer 1

a) f(1) =

5.1 - 2
5 - 2
R = 3


b)f(-3) =

5.(-3) - 2
-15 - 2
R = -17


c) f(0) =

5.0 - 2
0 - 2
R = -2

d) f(6) =

5.6 - 2
30 - 2
R = 28

e) f(2/5) =
2/5 = 0,4

5 .0,4 - 2
2 - 2
R = 0


f) f(8) =
5.8 - 2
40 - 2
R = 38
