Question

Especifique os coeficientes angulares e lineares das funções:

a) y = 3x + 81 -
b) f(x) = -10 +11x -
c) f(x) = -2x + 13 -
d) f(x) = 7x -

Answer 1

f(x) = ax + b ou y = ax + b

Coef. angular = a

Coef. linear = b

a) y = 3x + 81

a = 3

b = 81

b) f(x) = - 10 + 11x

a = 11

b = - 10

c) f(x) = - 2x + 13

a = - 2

b = 13

d) f(x) = 7x

a = 7

b = 0
