Quadratic Functions
Which of the following is a quadratic function?
f(x)=2x−1f(x)=2x-1f(x)=2x−1
h(x)=x(x+4)h(x)=x(x+4)h(x)=x(x+4)
Which of the following quadratic functions has a vertex (2,3)?(2,3)?(2,3)?
f(x)=x2+2f(x)=x^2+2f(x)=x2+2
f(x)=2(x−2)2+3f(x)=2(x-2)^2+3f(x)=2(x−2)2+3
This refers to polynomial functions with a degree 2.

f(x)=3x+2f(x)=3x+2f(x)=3x+2
f(x)=x2f(x)=x^2f(x)=x2
f(x)=3(x−3)(x+2)f(x)=3(x-3)(x+2)f(x)=3(x−3)(x+2)
f(x)=(x2−1)(x2−1)f(x)=(x^2-1)(x^2-1)f(x)=(x2−1)(x2−1)
f(x)=2(x−1)2+2f(x)=2(x-1)^2+2f(x)=2(x−1)2+2
f(x)=(x2−1)(x+1)f(x)=(x^2-1)(x+1)f(x)=(x2−1)(x+1)
f(x)=2x3−1f(x)=2x^3-1f(x)=2x3−1
h(x)=(x+3)(x+1)h(x)=(x+3)(x+1)h(x)=(x+3)(x+1)
f(x)=2x2−1f(x)=2x^2-1f(x)=2x2−1
h(x)=x2(x+4)h(x)=x^2(x+4)h(x)=x2(x+4)
f(x)=2(x−1)+2f(x)=2(x-1)+2f(x)=2(x−1)+2
f(x)=(2x)2−3f(x)=\left(2x\right)^2-3f(x)=(2x)2−3
It is done.
