How do you find the axis of symmetry, and the maximum or minimum value of the function #f(x) =x^2 + 3#?
The answer can be derived without any calculations!
For a quadratic; if the
Your equation has a positive
Consider the standard form equation of
There is no term for
Suppose for your question there was no constant. Then the minimum would be at
The constant of 3 lifts the graph up by 3 from this point. Thus the minimum is at:
