Question

Use a graphing calculator to find the value of f(x) when x = 1 for the function f(x)=x2-1.

Answer 1

To find the value of f(x) when x = 1 for the function f(x) = x^2 - 1 using a graphing calculator, enter the function, use the calculate feature or the table of values to find f(1), which is 0.

Step-by-step explanation:

To find the value of f(x) when x = 1 for the function f(x) = x2 - 1, you can follow these steps:

1. Turn on your graphing calculator.
2. Enter the function f(x) = x2 - 1 into the calculator by pressing the 'Y=' button and typing in the equation.
3. After the function is entered, you can calculate the value for x = 1 directly by using the calculator's calculate feature or by looking at the table of values.
4. To use the calculate feature, you can typically press the 'TRACE' or 'CALC' button and then type
5. 1
6. for
7. x
8. . The calculator will then display the corresponding value of
9. f(x)
10. , in this case,
11. f(1)
12. .
13. To check using the table of values, press the 'TABLE' button after entering the function in the 'Y=' screen. Scroll to x = 1 to find the value for f(1).

In this case, if you substitute x = 1 into the function f(x) = x2 - 1, you'd perform the calculation 12 - 1, which equals 0.
