Question

Siga a função definida por f(x) = 3x + 1. Calcule
A, f(0) D, f(-4)
B,f(2) E, f(15)
C, f (-1) F, f(20)


UUUUUURGEEEENTE!!!!!

Answer 1

f(x)=3x+1

f(0)=3.(0)+1
f(0)=1

f(2)=3.(2)+1=
f(2)=6+1
f(2)=7

f(-1)=3.(-1)+1
f(-1)=-3+1
f(-1)=-2

f(-4)=3.(-4)+1
f(-4)=3(-4)+1
f(-4)=-12+1
f(-4)=-11

f(15)=3.(15)+1
f(15)=45+1
f(15)=46

f(20)=3.(20)+1
f(20)=60+1
f(20)=61
