Answer:
Please check the explanation.
Step-by-step explanation:
Show that 4x - x² - 7 is always negative.
Given
4x - x² - 7
4x - x² - 7 is always negative because:
- -x²-7 will alwas be negative for all the values of x,
- The value of - x² - 7 will always be less than 4x for all the values of x
Hence, 4x - x² - 7 is always negative
For example,
let suppose we enter x = 1
let suppose we enter x = -1
