Final answer:
To evaluate the given function y = x^2 - 2x + 5 for x = 3, substitute 3 for x in the function and simplify the expression to find y = 8.
Step-by-step explanation:
To evaluate the given function y = x^2 - 2x + 5 for x = 3, substitute 3 for x in the function.
So, y = (3)^2 - 2(3) + 5.
Simplifying further, y = 9 - 6 + 5 = 8.
