Question

seja D (f)= {-3,-2,-0,2,3}^
Calcule :f (x)=-3x+1

Answer 1

Seja D (f)= {-3,-2,-0,2,3}

Calcule :f (x)=-3x+1

x=-3 ==> f(-3) = -3(-3)+1 = 9+1 ==> 10
x=-2 ==> f(-2) = -3(-2)+1 = 6+1 ==> 7
x=0 ==> f(0) = -3(0)+1 = 0+1 ==> 1
x=2 ==> f(-2) = -3(2)+1 = -6+1 ==> -5
x=3 ==> f(3) = -3(3)+1 = -9+1 ==> -8
