Question

Determine algebricamente o(s) zero(s) de cada uma das seguintes funções:
a) f(x) = 2x-3                b) y= -2/3x+1

Answer 1

$(a)\;f(x)=2x-3\\\\ 0=2x-3\\\\ 2x=3\\\\ \boxed{x=\dfrac{3}{2}}\\\\ \hspace{2.0cm}(b)y=-\dfrac{2}{3x}+1\\\\ 0=-\dfrac{2}{3x}+1\\\\ 1=\dfrac{2}{3x}\\\\ 3x=2\\\\ \boxed{x=\dfrac{3}{2}}$
