Question

Dada a função f(x) = 5x - 3x, determine:
f(2) + f(3) - f(5)

Answer 1

Resposta:

0.

Explicação passo-a-passo:

f(x)= 5x-3x

f(2)= 5.2-3.2 = 10-6 = 4

f(3)= 5.3-3.3 = 15-9 = 6

f(5)= 5.5-3.5 = 25-15 = 10

f(2) + f(3) - f(5) = 4 + 6 - 10 = 0

Answer 2

f(□) = 5×□ - 3×□

f(2) = 5×2 - 3×2 = 10 - 6 = 4

f(3) = 5×3 - 3×3 = 15 - 9 = 6

f(5) = 5×5 - 3×5 = 25 - 15 = 10

f(2) + f(3) - f(5) = 4 + 6 - 10 = 0
