8. a cubic function with a leading coefficient of -2, with one positive zero.

Example:           - 2x³ + 10x²

Step-by-step explanation:

1.A cubic function is a polynomial of degree 3 in one variable. This means that the highest exponent of the variable is 3: x³

2. Leading coefficient is the coefficient of the term with the highest exponent: in ax³ the leading coefficient is a.

3. General form of a cubic function: ax³ + bx² + cx + d, where a ≠ 0

4. Zeros of a polynomial function are the values of x for which the polynomial values zero: ax³ + bx² + cx + d = 0

5. When the polinomial is factored you can tell easily which the zeros are.

This is how a factored cubic function looks: a(x - x₁)(x - x₂)(x - x₃), where a is the leading coefficient, and x₁, x₂, and x₃ are the three zeroes of the function.

With that, you can write a cubic function with the restrictions stated:

         result: f(x) = - 2( x -5)(x - 0)(x -0) = -2(x - 5)(x)(x)

         - 2x³ + 10x²

i dont know their was no answer choice jiggaboo

(im black)

step-by-step explanation:

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
