Answer:

A.

Step-by-step explanation:

A is the only correct answer. If the number 15 were involved in the multiplication the fraction would be 1/2, or the number 15 would be used. Because 15 is not 1/5th of 30, the only answer would be A, which is the only one that uses that fraction.

The junior and senior class officers are sponsoring a homecoming dance. The total cost for the facilities and catering is $45 pe

larisa86 [58]

Answer:

Domain is (0,∞)

Range is (45, ∞)

Step-by-step explanation:

Let x represents the number of persons and f(x) represents the average cost per person,

∵ Fixed cost = $ 2500

Also, additional cost is $ 45 per person,

So, the total cost for x persons ( in dollars ) = fixed deposit + additional cost for x persons,

= 2500 + 45x

$\text{Average cost for x persons}=\frac{\text{Total cost}}{x}$

$\implies f(x)=\frac{2500+45x}{x}$

Which is a rational function,

∵ A rational function is defined for all real numbers except those for denominator = 0

Denominator of f(x) = x

So, f(x) is defined for all real numbers except x ≠ 0,

Now, the cost can not be negative,

⇒ x > 0

Hence, the domain for f(x) is (0, ∞)

Again,

$f(x)=45+\frac{2500}{x}$

If $x\rightarrow \infty$

$f(x)\rightarrow 45$

So, 45 < f(x) < ∞

i.e., range of f(x) is (45, ∞)
