Step-by-step explanation:
he missed 25%
if 4 = 25% then 16 questions total
4*4=16 and 25% * 4 = 100%
Answer: 3x^3 -8*x^2 + 8*x + 3
Step-by-step explanation:
The standard form for a plolynomial is:
a*x^n + b*x^(n-1) + c*x^(n - 2) ........
We have:
(x-1)(3x^2-5x-3)
this is equal to:
3*x^3 - 5*x^2 + 3*x - 3*x^2 +5*x + 3
where the thing that i did is distribute the multiplication
this is equal to:
3x^3 -8*x^2 + 8*x + 3
<span>The domain tells us which x values we can use in the equation. In this case, there is no x value that will result in the function being undefined, so the domain is all real numbers.
No matter what x we plug into our function, there are some y values that we will never receive- such as a negative number. The graph of this function is an upward opening parabola with its vertex at (2,2). Since the lowest y value we can obtain from this equation is 2, and it continues on toward infinity in the positive direction, the range is 2 to infinity.</span>
