Sagot :
[tex](1)\\f(x)=a\cdot x^2\ \ \ and\ \ \ f(5)=75\\\\75=a\cdot 5^2\ \ \ \Leftrightarrow\ \ \ a= \frac{75}{25}=3\\\\ \ \ \Rightarrow\ \ \ f(x)=3x^2\ \ \ \Rightarrow\ \ \ f(4)=3\cdot4^2=3\cdot16=48\ \ \ \Rightarrow\ \ \ Ans.\ C.\\\\(2)\\6y=9x^2 \ \ \ \ \Leftrightarrow\ \ \ \ \ \frac{y}{x^2}= \frac{9}{6}= \frac{3}{2} \ \ \Rightarrow\ \ \ Ans.\ C. \\\\(3)\\g(x)=a\cdot x^2\ \ \ and\ \ \ g(6)=108\\\\108=a\cdot 6^2\ \ \ \Leftrightarrow\ \ \ a= \frac{108}{36} =3\ \Rightarrow\ \ \ g(x)=3x^2\ \Rightarrow\ \ \ Ans.\ B.[/tex]
