Question

Determine o coeficiente angular e o termo constante de cada função abaixo:
a) F(x) = 4x -5
b) F(x) = -3x + 4
c) F(x) = x - 1
d) F(x) = 5x
e) F(x) = 7
f) y = -3 - x
g) y = - 10
h) F(x) = -2x

Answer 1

na função F(x)=ax+b
a⇒ coeficiente angular
b⇒ termo  constante, também chamado de coeficiente linear

$a) \\ f(x)=4x-5 \\ coeficiente~~angular\mapsto4 \\ termo~~constante\mapsto-5 \\ \\ b) \\ f(x)=-3x+4 \\ coeficiente~~angular\mapsto-3 \\ termo~~constante\mapsto+4 \\ \\ c) \\ f(x)=x-1 \\ coeficiente~~angular\mapsto1 \\ termo~~constante\mapsto-1 \\ \\ d) \\ f(x)=5x \\ coeficiente~~angular\mapsto=5 \\ \\ e) \\ f(x)=7 \\ termo~~constante\mapsto7 \\ \\ f) \\ f(x)=-3-x \\ f(x)=-x-3 \\ coeficiente~~angular\mapsto-1 \\ termo~~constante\mapsto-3 \\ \\ g) \\ f(x)=-10 \\ termo~~constante\mapsto-10$ 

$h) \\ f(x)=-2x \\ coeficiente~~angular\mapsto-2$
