Answer:
- f(-2) = - 3 is the greatest value in the given range
-------------------------------
Given
- Function y = x² - 7,
- Domain x = {- 2, 0, 1 }.
Find the value for each domain and compare
- f(-2) = (-2)² - 7 = 4 - 7 = - 3
- f(0) = 0² - 7 = 0 - 7 = - 7
- f(1) = 1² - 7 = 1 - 7 = - 6
The greatest value of the function is - 3.
