x = 2

<em>right</em><em> </em><em>option</em><em> </em><em>is</em><em> </em>(E).

Step-by-step explanation:

f(x) = x³ - 3x² + 12 in interval [-2, 4]

{taking f'(x) by doing derivative of f(x)}

f'(x) = 3x² - 6x

.•. f'(x) = 0

0 = 3x² - 6x

0 = 3x(x - 2)

0 = x - 2

x = 2

find the slope-intercept form of the line whose slope os 4 and that passes through the point (-9,12)​
Trava [24]

Answer:

y = 4x+48

Step-by-step explanation:

Slope intercept form is y=mx+b. We already know the value for m(4), so we can plug in the x and y coordinates for x and y in the equation. This gives us 12=4(-9)+b. Solve for b to get 48

Find the slope of the line that passes through (14, -26) and (15, 14).
tatuchka [14]

Answer:

Slope is 40

Full equation: y=40x-586

Step-by-step explanation:

Slope is y2-y1/x2-x1

14 is x1

-26 is y1

15 is x2

14 is y2

14-(-26)/15-14

40

So the slope is 40

To find the equation

y=40x+b

14=15(40)+b

14=600+b

b=-586

Equation:

y=40x-586
