Use the graph of f "(x) below to state x-coordinates of the inflection points for the graph of f(x).

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: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
