I need help on question 1 of symbolic representation

Mathematics

Step-by-step explanation:

Symbolic representation here means defining the function using variables such as x and y (or f(x)).

An example would be f(x) = 4x+3.

Here, we are given two points on the linear function (which is a line), namely

f(4)=5,  which implies P1(4,5) is a point P1 on the line, and

f(-7)=5, which implies P2(-7,5) is another point P2 on the line.

With the usual notation that

P1 has the coordinates (x1,y1)

P2 has the coordinates (x2,y2),

we see that

x1=4, y1=5

x2=-7, y2=5

which can be used in the standard equation for a line given two points P1 and P2:

m = slope = (y2-y1)/(x2-x1) = (5-5)/(-7-(4)) = 0/11 = 0

equation of the line

y = m(x-x1) + y1, which simplifies to

y = 0(x-4) + 5, which further simplifies to

y=5   (which is a horizontal line).

Answer:

f(x) = 0x + 5

Step-by-step explanation:

Lets use the slope formula to determine the slope of this graph:

m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1} } \\\\m=\frac{5-5 }{4-(-7)} \\\\m=0

SO we know the slope is zero.

If we know the slope is zero, then the y intercept must be at 5.

So the equation would be:

f(x) = 0x + 5

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
