Question

Considere a função f(x) = 5 − 4. Calcule f(−1) e f(10).

Answer 1

Se for:

f(x)= 5x -4

f(-1)= 5.(-1) - 4

f(-1)= - 5 -4

f(-1)= - 9

f(10)= 5.10 -4

f(10)= 50 -4

f(10)= 46

Answer 2

Considere a função f(x) = 5x − 4. Calcule f(−1) e f(10). F(-1)= 5.(-1)-4= - 5-4= - 9 F(10)= 5.10-4= 50-4= 46
