Intercept: 4
Minimum value:
Explanation:
From the equation, any number behind
Next, complete the square so that the equation is in the form of
If you don't know how to complete a square, it's like this:
- Divide the coefficient of
x by2 - Take the square out of the
x , so you will get(x-2)^2 - Then square the
2 inside the bracket, which gets you(x-2)^2-4+4 - Finally simplify the equation.
(x-2)^2
Since there is no number after the brackets, the minimum value of
Minimum points=
(Always switch the negative signs into positive and vice versa for the completed square!)
