Answer:
f(x)=(3x-5)(4x+2) is a quardatic function.
Step-by-step explanation:
f(x)=(3x-5)(4x+2)
simplify
f(x)=3x(4x+2)-5(4x+2)
f(x)=[tex]12x^{2} +6x-20x-10[/tex]
adding the coefficients of x, we get
f(x)=[tex]12x^{2} -14x-10[/tex]
which is quardatic equation since it contains the terms 12[tex]x^{2}[/tex].
