Question

Dada a função f(x)=5x-11 determine


A) F(-19)=

B) F(3,4)=

C) F(-2/7)=

Answer 1

Dada a função f(x)=5x-11 determine

a) f(-19) = 5*(-19) - 11 = -106

b) f(3,4) = 17 - 11 = 6

c) f(-2/7) = -10/7 - 77/7 = -87/7

Answer 2

f(-19) = 5.(-19) - 11
f(-19) = -95 - 11
f(-19) = -106
==================
f(3,4) = 5 (3,4) - 11
f(3,4) = 17 - 11
f(3,4) = 6
==================
f(-2/7) = 5. (-2/7) - 11
f(-2/7) = -87/7
