Question

Dada a função f(x)=-x+6, determine a)f(-2) b) f(-1/3) c) f(-4) d)f (0) e)f (1) f) f(x) =-8 g) f(x) =1/2 h) f(x)=4 i) f(x)= 0,2 j) (x)=-3/3

Answer 1

a) f(-2) = -2 + 6 —> f(-2) = 4

b) f(-1/3) = -1/3 + 6 —> f(-1/3) = -17/3

c) f(-4) = -4 + 6 —> f(-4) = 2

d) f(0) = 0 + 6 —> f(0) = 6

e) f(1) = 1 + 6 —> f(1) = 7

f) f(x) = -8 —> x + 6 = -8 —> x = -8 - 6 —> x = -14

g) f(x) = 1/2 —> x + 6 = 1/2 —> x = 1/2 - 6 —> x = -11/2

h) f(x) = 4 —> x + 6 = 4 —> x = 4 - 6 —> x = -2

i) f(x) = 0,2 —> x + 6 = 0,2 —> x = 0,2 - 6 —> x= -5,8

j) f(x) = 3/3 —> x + 6 = 3/3 —> x = 3/3 - 6 —> x = -5

Espero ter ajudado, bons estudos! ♡
