Answer:

all values! x ∈ R

Step-by-step explanation:

The derivative f'(x) = 6x²-6x+12 is a parabola opening upward, with its (positive!) minimum at (0.5, 11.5). If the derivative is always positive, the function must be increasing everywhere!

Which statements are true from the graph ? Check all that apply:

Flura [38]

The statements that are true from the graph are:

The line is horizontal
The line goes through (4, 4 )
The y- values are all 4

<h3>Calculations and Parameters</h3>

Given the graph, we can note some things:

There is a line with a slope of zero.
This is a horizontal line parallel to the x-axis.
The equation of the line is y = c

c is the value of the y- coordinates the line passes through.

The line passes through (0, 4 ) with a y- coordinate of 4

Therefore, the equation of the line of y= 4
