The quadratic function:
[tex]f(x)=ax^2+bx+c,\ a\neq0[/tex]
Answer: [tex]u(x)=-x+3x^2-8=3x^2-x-8[/tex]
Answer:
[tex]u(x) = -x + 3x^2 - 8[/tex]
Step-by-step explanation:
Quadratic function is in the form of [tex]y=ax^2+bx+c[/tex] with largest exponent as 2
[tex]u(x) = -x + 3x^2 - 8[/tex] can be written as [tex]u(x) =3x^2-x - 8[/tex]
is in the form of y=ax^2 + bx +c with largest exponent 2. so it is quadratic function.
[tex]v(x) = 2x^2 + 8x^3 + 9x[/tex]. It is not quadratic because it has largest exponent 3.
[tex]y(x) = x^2 + 3x^5 + 4[/tex]. It is not quadratic because it has largest exponent 5.
[tex]z(x) = 7x^2 + 2x^3 - 3[/tex] It is not quadratic because it has largest exponent 3.
