What are the discontinuities of the function f(x) = the quantity x squared minus 16 over the quantity 4x minus 24?
ANEK [815]
Dividing x^2 - 16 by 4x - 24  gives the quotient (1/4)x + 3/2

y = (1/4)x + 3/2  would be an asymptote  ( discontinuity)

Another would be a vertical discontinuity  when x =  6  (this would make the denominator 4x-24  = 0.

Write the equation of a line that is parallel to 4x-2y=3 and is passing through the point (2,1)
Temka [501]

Answer:

y= 2x -3

Step-by-step explanation:

Let's rewrite the given equation into the form of y=mx+c, so that we can find the gradient of the line. In this form, m (coefficient of x) is the gradient.

4x -2y= 3

2y= 4x -3

<em>Divide</em><em> </em><em>by</em><em> </em><em>2</em><em> </em><em>throughout</em><em>:</em>

y = 2x - 1 \frac{1}{2}

Thus the gradient is 2.

Parallel lines have the same gradient thus the line would also have a gradient of 2.

Substitute m=2 into the equation:

y= 2x +c

To find the value of c, substitute a pair of coordinates.

When x=2, y=1,

1= 2(2) +c

1= 4 +c

c= 1 -4

c= -3

Thus, the equation of the line is y= 2x -3.
