Answer:
A) x - 4
B) x² - 4x
C) x³ - 2x² - 8x
D) 2x³ + 3x² - 32x + 15
Step-by-step explanation:
A)
x-intercepts: x = 4
Factors:
(x - 4)
B)
x-intercepts: x = 4, 0
Factor:
(x - 0)(x - 4)
x² - 4x
C)
x-intercepts: x = 4, 0, -2
Factor:
(x - 0)(x - 4)(x + 2)
(x² - 4x)(x + 2)
x³ - 4x² + 2x² - 8x
x³ - 2x² - 8x
D)
x-intercepts: x = 3, ½, -5
Factor:
(x - 3)(2x - 1)(x + 5)
(2x² - 6x - x + 3)(x + 5)
(2x² - 7x + 3)(x + 5)
2x³ - 7x² + 3x + 10x² - 35x + 15
2x³ + 3x² - 32x + 15
Answer:
Okay so we need to simplify, which means to find the smallest possible number but for it to be the same.
Step-by-step explanation:
An example is: 12/20 = 3/4
It equals that because 12/20 can be rewritten as 3/4.
Another example is: 24/30 = 4/6
It equals that because 4 can be added into 24 6 times, so it would be written as 4/6.
Another example is: 15/45= 5/15
It equals that because 5 can be fitted into 15 3 times, so the answer is 5/15.
I hope this helps
Answer: 8 5/6, 177/20, 8.839 and 8.99
The correct answer is going to be C.
A={a,b,c}, B={9,16,25}, and f={(a,9),(b,16),(a,25)}. True or false, f is a function from A to B?

Answer: False</h3>
Explanation:
The input x = a leads to multiple outputs y = 9 and y = 25 at the same time. This is due to the points (a,9) and (a,25) in the set f.
A function can only be possible when any x input leads to exactly one y output only. You'd need to get rid of either (a,9) or (a,25) to make this a function.
