Question

1. what is the purpose of using the maximum or minimum feature in a ti calculator while graphing quadratic functions?

a. to find the asymptotes
b. to find the vertex
c. to adjust the graphs appearance
d. to view specific values of y for given x-values

Explanation:

A quadratic function \(y = ax^{2}+bx + c\) (\(a
eq0\)) has a vertex. If \(a>0\), the parabola opens upwards and the vertex is the minimum point. If \(a < 0\), the parabola opens downwards and the vertex is the maximum point. The "maximum" or "minimum" feature on a TI - calculator is used to find the vertex of the quadratic function.
Asymptotes are for rational or other non - quadratic functions (like hyperbolas in some cases). Adjusting the graph's appearance is usually done through window settings. Viewing specific \(y\) values for given \(x\) values is done using the "value" or "trace" feature.

Answer:

B. To find the vertex
