What are the vertical and horizontal asymptotes for the function f(x)=<br> 3x2/x2-4
Alecsey [184]

Answer:  f(x) will have vertical asymptotes at x=-2 and x=2 and horizontal asymptote at y=3.

Step-by-step explanation:

Given function: f(x)=\dfrac{3x^2}{x^2-4}

The vertical asymptote occurs for those values of x which make function indeterminate or denominator 0.

i.e. x^2-4=0\Rightarrow\ x^2=4\Rightarrow\ x=\pm2

Hence, f(x) will have vertical asymptotes at x=-2 and x=2.

To find the horizontal asymptote , we can see that the degree of numerator and denominator is same i.e. 2.

So, the graph will horizontal asymptote at y=\dfrac{\text{Coefficient of }x^2\text{ in numerator}}{\text{Coefficient of }x^2\text{ in denominator}}

i.e. y=\dfrac{3}{1}=3

Hence, f(x) will have horizontal asymptote at y=3.

A senior employee who works 16 hours earns $39.50 more than a junior employee who works 18 hours. The senior employee earns $14
Vlad [161]

Answer:hourly pay for the junior employee in dollars and cents=$10.25

Step-by-step explanation:

Step 1

Total amount  senior employee is being paid = amount per hour x hours worked

 = $14 × 16 = $224.00

 Total amount of junior employee  since he/ she collects $39.50 less than senior employee= $224.00 - $39.50

                             = $184.50

 

 

Step 2

hourly pay of junior colleague= Total pay of junior colleague/ Hours worked

 =$184.50 / 18 hours

 = $10.25 per hour
