Answer:
<h2>0 and 4.</h2>Step-by-step explanation:
By mathematical definition, an inflection points is where the second derivative is null, that is, , when that happens, we can say there are inflections points.
So, the graph is showing the function of the second derivative of the original one. As we said, where the second derivative is null, there is an inflection points. You can observe in the image attached, that when and
, the function which represents the second derivative, is null, that means there are inflection points at those coordinates.
Therefore, the answer is 0 and 4.

Answer:
x = 3
Step-by-step explanation:
Square both sides of the equation
(x - 3)(x - 5) = 0
x = 3 or 5
Now, you must always check your results because a result may not satisfy the original equation.
If x = 3, then and 3 - x = 3 - 3 = 0
So 3 satisfies the original.
If x = 5, then , but 3 - x = 3 - 5 = -2. Therefore, 5 does NOT satisfy the original equation.
That means that x = 3 is the solution to the equation.
Answer:
(or 6.25)
Step-by-step explanation:
Let's do a simple square problem to see the relationship between the elements of the resulting equation...
As you see, the number of 'x' (6) is the double of the numeric part of the binomial expression (3), while the numeric-only part (9) is the square of the numeric part of the binomial expression (3).
So, if we look at the formula from the problem, we see the the number of 'x' is 5. To obtain the C value, we need to divide the 5 by 2... then get the square value of the result.
