Vladimir79 [104]

Answer:

choice C: x2 -3x -3

Step-by-step explanation:

(3x^2-7x+2)-(2x^2-4x+5)

becomes

3x^2-7x+2 -2x^2+4x-5

adding

3x^2-2x^2 -7x+4x +2-5

which is

x^2 -3x -3

4 A curve has equation y=x^3 - 2x² +5. Find the coordinates of its two stationary points.

vodomira [7]

Answer:

Stationary points are (0, 5) and (4/3, 103/27)

Step-by-step explanation:

At stationary point (turning point), dy/dx :

$y = {x}^{3} - 2 {x}^{2} + 5 \\ \frac{dy}{dx} = 3 {x}^{2} - 4x \\ \\ \frac{dy}{dx} = x(3x - 4)$

but dy/dx = 0:

$x(3x - 4) = 0 \\ either \: x \: is \: 0 \: and \: (3x - 4) = 0 \\ x = 0 \\ and \\ 3x - 4 = 0 \\ x = \frac{4}{3}$

let y = x³ - 2x² + 5:

$when \: x \: is \: 0 \\ y = 5 \\ when \: x \: is \: \frac{4}{3} \\ \\ y = {( \frac{4}{3}) }^{3} - 2 {( \frac{4}{3} )}^{2} + 5 \\ \\ y = \frac{103}{27}$
