f(x) = x ^ 0.5 * 6.3 - sqrt(2) does not work properly in the graph for me. does anyone know why or does it happen to anyone else?

if you want the equation copy this here: f(x) = x ^ 0.5 * 6.3 - sqrt(2)

or you can look at this $${f}{\left({\mathtt{x}}\right)} = {{\mathtt{x}}}^{{\mathtt{0.5}}}{\mathtt{\,\times\,}}{\mathtt{6.3}}{\mathtt{\,-\,}}{\sqrt{{\mathtt{2}}}} \Rightarrow {f}{\left({\mathtt{x}}\right)} = {\frac{\left({\mathtt{63}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{x}}}}{\mathtt{\,-\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{{\mathtt{2}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)}\right)}{{\mathtt{10}}}} \Rightarrow {f}{\left({\mathtt{x}}\right)} = {\frac{\left({\mathtt{63}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{x}}}}{\mathtt{\,-\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{{\mathtt{2}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)}\right)}{{\mathtt{10}}}}$$
