Question

Dada a função defina por f(x)=x2-x,determine:
a)f(-2)
b)f(0)

Answer 1

$\large\bm{f(x) = {x}^{2} - x }$

Vamos lá

A)

$\large\bm{f( - 2) =\left( - 2\right)^{2} + 2 } \\ \large\bm{f( - 2) = 4 + 2} \\ \large\bm{f( - 2) = 6}$

B)

$\large\bm{f(0) = {0}^{2} + 0} \\ \large\bm{f(0) = 0 + 0} \\ \large\bm{f(0) = 0}$
