Question

2) dada a função f(x) = -7x+8, calcule:
2.f(0)-f(3) + f (1). f(-10)​

Answer 1

Resposta:

-74

Explicação passo-a-passo:

$f(0)=-7\;.\;0+8=0+8=8\\f(3)=-7\;.\;3+8=-21+8=13\\f(1)=-7\;.\;1+8=-7+8=1\\f(-10)=-7\;.\;-10+8=70+8=78\\\\\\2\;.\;f(0)-f(3)+f(1)-f(-10)=2\;.\;8-13+1-78=16-13+1-78=-74$
