Question

2. Sendo F(x)=38x-1 de termine :

a) f(2) =
b)f(0)=
c)f(-1)=
d)f(x)= 0
e)f(x)=-2​

Answer 1

f(x) = 38x - 1

a) f(2) = 38(2) - 1

f(2) = 76 - 1

f(2) = 75

b) f(0) = 38(0) - 1

f(0) = 0 - 1

f(0) = - 1

c) f(-1) = 38(-1) - 1

f(-1) = - 38 - 1

f(1) = - 39

d) 38x - 1 = 0

38x = 1

x = 1/38

e) 38x - 1 = - 2

38x = - 2 + 1

38x = - 1

x = - 1/38
