Question

Determine as raízes da função

Answer 1

Explicação passo-a-passo:

As raízes são "quanto f(x)=y=0":

g)

$3x+2=0\\\\3x=-2\\\\x=-\dfrac{2}{3}$

h)

$-5x-1=0\\\\-5x=1\\\\x=-\dfrac{1}{5}$

i)

$-x=0\\x=0$

j)

$2+3x=0\\\\3x=-2\\\\x=-\dfrac{2}{3}$

k)

$\dfrac{2}{3}x+2=0\\\\\dfrac{2}{3}x=-2\\\\x=-2\times\dfrac{3}{2}\\\\x=-3$

l)

$2x-1=0\\\\2x=1\\\\x=\dfrac{1}{2}$
