Question

1. how do you access the calc menu to find the vertex of a parabola on a ti calculator?

a. open the math menu
b. press 2nd then trace
c. use the window settings
d. press trace

Explanation:

Step1: Recall TI - calculator operations

On a TI calculator, to access the CALC menu for finding the vertex of a parabola, the standard operation is to press the '2ND' key followed by the 'TRACE' key.

Step2: Analyze each option

• Option a: Opening the 'Math' menu is not the correct way to access the CALC menu for vertex - related operations.
• Option b: Pressing '2ND' then 'TRACE' is the correct sequence to access the CALC menu.
• Option c: Using the 'WINDOW' settings is for adjusting the viewing window of the graph, not for accessing the CALC menu.
• Option d: Pressing 'TRACE' alone does not access the CALC menu.

Answer:

B. Press '2ND' then 'TRACE'
