<span>The graph you plotted is the graph of f ' (x) and NOT f(x) itself. </span>
Draw a number line. On the number line plot x = 3 and x = 4. These values make f ' (x) equal to zero. Pick a value to the left of x = 3, say x = 0. Plug in x = 0 into the derivative function to get
f ' (x) = (x-4)(6-2x) f ' (0) = (0-4)(6-2*0) f ' (0) = -24
So the function is decreasing on the interval to the left of x = 3. Now plug in a value between 3 and 4, say x = 3.5
The function is increasing on the interval 3 < x < 4. The junction where it changes from decreasing to increasing is at x = 3. This is where the min happens.
Pretty sure it’s G cause everyone does math problems at a different pace. And also some math problems are more work compared to others ig. so G would have the most variability for the data
Area of triangle=1/2 times base times height given that area=24 and height=6 24=1/2 times base times 6 24=1/2 times 6 times base 24=3 times base divide both sides by 3 8=base the base is 8 units long
