Using mathematical induction prove that n! > 5n for n > or equal to 4

see explanation

Step-by-step explanation:

To find the y- intercept let x = 0

y = 0² - 100 = - 100 ⇒ (0, - 100) ← y- intercept

To find the x- intercepts let y = 0, that is

x² - 100 = 0 ( add 100 to both sides )

x² = 100 ( take the square root of both sides )

x = ± = ± 10, thus

(- 10, 0 ), (10, 0 ) ← x- intercepts
