In B 5^2 = 25. There is no x anywhere.
In C f(x) = 2/x is a function of a reciprocal, not a quadratic.
In D f(x) = 2x^3 + 3x^2 - 5 is a cubic. A cubic is not a quadratic. The highest power of a quadratic is x^2
That leaves A. When you expand the brackets, you get
3(x^2 + 3x- 4x - 12)
2(x^2 - x - 12) when you remove the brackets you get
2x^2 - 2x - 24. The highest power of x is x^2. This is your quadratic.
A<<<< answer.
Answer:
J: 2/45
Step-by-step explanation:
You multiply the probabilities together then simplify
2/15 x 5/15
to get 10/225
simplify to get your answer of 2/45
Answer:
B, C, E
Step-by-step explanation:
This is correct. Trust me.
Answer:
Step-by-step explanation:
There are many such polynomials, but the one with leading coefficient of 1 is
y = (x+1)(x-1)(x-6) = x^3 - 6x^2 - x + 6
Not sure what you want to do with the 5, If that is the y-intercept, then since
(1)(-1)(-6) = 6, we will need
y = 5/6 (x^3 - 6x^2 - x + 6)
I think it’s B but don’t at me
