Answer:

Step-by-step explanation:

1) The function f(x) = x is a straight line rising to the right and passing through the origin at an angle of 45 degrees This means this it passes though the points ..... (-2, -2), (-1, -1), (1, 1), (2, 2) .......

If g(x) = f(x) + 4 then g(x) will be a straight line parallel to f(x) where each point on g(x) is 4 units vertically up from each point on f(x). Its a translation of f(x) up 4 units.

The slope of both graphs is 1.

2) This line (g)x passes through the origin but has slope 1/3.

X-3 and 2x-1 are factors of 2x^3-px^2-2qx+q. Find the values of p and q.

Nonamiya [84]

Answer:

p =1

q = 9

Step-by-step explanation:

f(x) = 2x³ - px² + 2qx + q

(x - 3) is a factor of f(x)

⇒f(3) = 0

2(3)³ - p*3² - 2q*3 +q = 0

2*27 - 9p - 6q + q = 0

54 - 9p - 5q = 0

-9p - 5q = -54 -------------------(I)

(2x - 1) is a factor of f(x)

2x - 1 = 0

2x = 1

$\st x = \dfrac{1}{2}$

f(1/2) = 0

$2*(\dfrac{1}{2})^{3}-p*(\dfrac{1}{2})^{2}-2q*\dfrac{1}{2}+q=0\\\\2*\dfrac{1}{8}-p*\dfrac{1}{4}-q+q = 0\\\\\dfrac{1}{4}-\dfrac{1}{4}p =0\\\\[Multiply the entire equation by 4]\\\\4*\dfrac{1}{4}-4*\dfrac{1}{4}p=0\\\\$

1 - p = 0

-p = -1

p = 1

Substitute p =1 in equation (I)

-9*1 - 5q = -54

-9 - 5q = -54

-5q = -54 + 9

-5q = -45

q = -45/(-5)

q = 9
