Quadratic Functions and Applications
Graph each of the following parabolas, and use the TRACE feature to find whole number estimates of the vertex. Then either complete the square or use $\left(-\frac{b}{2 a}, \frac{4 a c-b^{2}}{4 a}\right)$ to find the vertex. (a) $f(x)=x^{2}-6 x+3$ (b) $f(x)=x^{2}-18 x+66$ (c) $f(x)=-x^{2}+8 x-3$ (d) $f(x)=-x^{2}+24 x-129$ (e) $f(x)=14 x^{2}-7 x+1$ (f) $f(x)=-0.5 x^{2}+5 x-8.5$
