<em>Question No 7</em>
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

Answer: -5.27 + (-3.32) = -8.59 and -5.6 + 27.4 = 21.8

f(n) = 1 + 3(n-1) = 1 + 3n - 3 = 3n -2
f(22) = 3(22)-2 = 66-2 = 64
