Question

1) Tendo F(x)= -8x²+6x+10 , calcule:

A) F(8)=
B) F(-10)=
C) F(0)=

Pessoal me ajuda a responde isso!!!

Answer 1

F(x) = -8x² + 6x + 10

F(8) = -8(8)² + 6(8) + 10
F(8) = -8(64) + 48 + 10
F(8) = -512 + 58
F(8) = -454

F (-10) = -8(-10)² + 6(10) + 10
F(-10) = -8(100) + 60 + 10
F(-10) = -800 + 70
F(-10) = -730

F(0) = -8(0)² + 6(0) + 10
F(0) = 0 + 0 + 10
F(0) = 10
