Given


Required
Find f(g(x))
If: 
Then:

Solve the denominator (take LCM)


It can be solved further as:



C = pi x d
So the border is about 3.1 x 20 = 62 inches
Answer:
The squared form is not a correct form of the quadratic function.
Step-by-step explanation:
Given some forms of quadratic equation. we have to choose the form which is not correct of the quadratic equation.
As the general form and the standard form of quadratic equation is
where a,b and c are constant.
Also, the vertex form is
where (a,b) is vertex.
Only the three forms of quadratic equation exist. No other form like squared form exist.
Hence, the squared form is not a correct form of the quadratic function.
