Step-by-step explanation:
Given the zero x = a of f(x) then f(a) = 0
(5)
f(9) =9³ - 8(9)² - 2(9) - 63 = 729 - 648 - 18 - 63 = 0
Hence x = 9 is a zero of the polynomial
(6)
2
- 3(- 3)³ - 36(- 3)² - 37(- 3) - 26 = 162 + 81 - 324 + 111 - 26 = 4 ≠ 0
Hence x = - 3 is not a zero of the polynomial
Answer: 24 | 8/9
Step-by-step explanation:
Answer:
There is a 60.00 percent probability of a particular outcome and 40.00 percent probability of another outcome.
Notice the x^-2, this is equal to 1/x^2. Then notice the y^0, any value raised to the zero power is equal to 1, ie n^0=1. So your expression is actually just:
8/x^2, the y value has no effect upon the output. They want you to evaluate, which must means calculate, the value when x=2 so:
8/(2^2)
8/4
