Question

Dada a função f={x,f(x)) € RxR|f(x)=3x+40},calcule a) f(-10) b f(2) c) f(0) d f(1/3

Answer 1

Olá,

f(x) = 3x + 40

a) f(-10) = 3*(-10) + 40
f(-10) = -30 + 40
f(-10) = 10

b) f(2) = 3*2 + 40
f(2) = 6 + 40
f(2) = 46

c) f(0) = 3*0 + 40
f(0) = 40

d) f(1/3) = 3*1/3 + 40
f(1/3) = 1 + 40
f(1/3) = 41

Bons estudos ;)
