Determine the vertical asymptote for the rational function f(x) = x - 4 over 2x + 3.
mr_godi [17]

Vertical asymptotes happen at x=a if the function is undefined at x=a.

This is a rational functions, and rational functions are not defined when the denominator is zero, since you can't divide by zero.

In this case, the denominator is zero if

2x+3=0 \iff 2x=-3 \iff x=-\drac{3}{2}

And thus the function has a vertical asymptote at x= -3/2

How do you work this out
oksian1 [2.3K]

Answer:

Below.

Step-by-step explanation:

To find the number of students in each grade you multiply the marks by the frequency density. The number of students is given by the area under the  rectangles.

So to find the number of students with grade U (< 160)  it is:

120 * 0.2 + 40*0.5

= 24 + 20

= 44.

The number for Grade E

= (200 - 160) * 0.5

= 40 * 0.5

= 20.

The others can be found in the same way.

Factor to find the zeros of the function defined by the quadratic expression.
wel
Hi there! The answer is A) x = 3 or x = 6

2 {x}^{2}  - 18x + 36 = 0
Divide by 2.

{x}^{2}  - 9x + 18 = 0
Factor.

(x - 3)(x - 6) = 0
Use the rule AB = 0 gives A = 0 or B = 0

x - 3 = 0 \:  \: or \:  \: x - 6 = 0 \\ x = 3 \:  \:   \:  \:  \:  \:  \:  \:  \: or \:  \: x = 6

The answer is A) x = 3 or x = 6
