Question

dada as função f(x)=x2-x com x e r e y e r calcule f(1)+3 f(-1) -5f (3)+f(0)​

Answer 1

Dada as função f(x) = x^2 - x com x e r e y e r calcule f(1)+3 f(-1) -5f (3)+f(0)​

f(1) = 1 - 1 = 0

f(-1) = 1 + 1 = 2

f(3) = 6

f(0) = 0

agora

f(1)+3 f(-1) -5f (3)+f(0)​

= 0 + 3*2 - 5*6 + 0 = -24
