Question

Identifique as coeficientes a e b em cada função

a) f(x)= 5x-3
b) f(x)= -2x+5
c) f(x)= 3x
d) f(x)= -6x

Answer 1

     Isa,

    As equações tem a forma
                   y = ax + b

    Por comparação
                                  EQUAÇÃO [f(x)]           COEFICIENTES
                                                                             a             b
                                       5x - 3                             5           - 3
                                    - 2x + 5                           - 2             5
                                       3x                                   3            0
                                     - 6x                                - 6             0
