Question

sendo f(x)=3× e g(x)=$\frac{1}{4}$× determine :
a)f(-4)
b)f($\frac{1}{3}$)
c)g(-3)
d)g($\frac{1}{2}$)

Answer 1

a) f(x) = 3x
f (- 4) = 3 (-4)
f(- 4) = - 12

b) f(x) = 3x
f (1/3) = 3 .1/3
f(1/3) = 3/3
f(1/3) = 1

c) g(x) = 1/4x
g( - 3) = 1/4 . (- 3)
g( - 3) = - 3/4

d) g(x) = 1/4x
g(1/2) = 1/4 . 1/2
g(1/2) = 1/8
