Compare function properties across representations, especially quadratic comparisons.
Compare two y-intercepts at x=0
Problem
Compare these \(y\text{-}\text{intercepts}\): \(A(x)=x^{2}-3x+5\); \(B(x)=2(x-1)^{2}+1\).
Big Picture
What this problem is really about
A y-intercept comparison holds the input fixed at zero for both functions. We’ll evaluate each complete rule at that shared input, especially any grouped expression, and compare the resulting outputs with a signed difference.
