Determine the absolute extrema of each function on the given interval. Illustrate your results by
sketching the graph of each function.
a) f(x) = x^2 − 4x + 3 , 0 ≤ x ≤ 3
b) f(x) = (x − 1)^2 , 0 ≤ x ≤ 2

you don't need calculus for this. It can just confirm your answers. these are just ordinary parabolas. Find the vertex, and check the values at the ends of the intervals.
