Answer:
Its definitely B 84.5
I took the test
Step-by-step explanation:
When you plot the given points, you obtain the graph attached. As you can see, the function has two turning points, so:
Minimum degree=(2 turning points)+1=3
Therefore, the minimum degree of a polynominal model is 3, and it can be expressed as below:
f(x)=ax³+bx+cx+d
The answer is:3
Answer:
Vertically angles
Step-by-step explanation:
Answer:
6x^2 + 3x + 21 = 3(2x^2 + x + 7)
Step-by-step explanation:
We have this as follows;
6x^2 + 3x + 21 = 3(2x^2 + x + 7)
The quadratic trinomial inside the bracket cannot be factored any further
so we have the present form as the correct answer
