Answer:

Step-by-step explanation:

f(x)=[tex]\frac{\sqrt{12x+1} }{4x-7}[/tex]

f([tex]\frac{1}{4}[/tex])=[tex]\frac{\sqrt{12*\frac{1}{4}+1 } }{4*\frac{1}{4}-7 }[/tex]

f([tex]\frac{1}{4}[/tex])=[tex]\frac{\sqrt{3+1} }{1-7}[/tex]

f([tex]\frac{1}{4}[/tex])=[tex]\frac{\sqrt{4} }{-6}[/tex]

f([tex]\frac{1}{4}[/tex])=[tex]\frac{2}{-6}[/tex]

∴f([tex]\frac{1}{4}[/tex])=[tex]\frac{-1}{3}[/tex]
