Question

Dada a Funcao f(x) = 5x - 3 determinar : a) f(0) b) f(-1) c) f -1/2

Answer 1

a) f(0) = 5*0-3 = -3
b) f(-1) = 5*(-1)-3 = -5-3 = -8
c) $f( \frac{-1}{2} )=5* \frac{-1}{2} -3= \frac{-5}{2} -3 = \frac{-5-6}{2} = \frac{-11}{2} = -5,5$

Answer 2

f(x) = 5x - 3

f(0) = 5 x 0 - 3 = 0 - 3 = - 3
f(- 1) = 5 x (- 1) - 3 = - 5 - 3 = - 8
f(- 1/2) = 5 x (- 1/2) - 3 = - 5/2 - 3 = - 5/2 - 6/2 = - 11/2
