The answer would 2, since you cannot divide anything by 0 as it would be undefined. 2 is the only number that gives you this option

Answer:

given rational function is undefined for x = 2

Step-by-step explanation:

The given rational function is

\frac{x^2-4}{2-x}

The rational function is undefined if the denominator is zero.

Hence, the given rational function is undefined if

2-x=0

Solve the equation for x

x=2

Therefore, the given rational function is undefined for x = 2

The function, y(r)=2.76r , is used to convert Russian rubles in Japanese yen, and the function, P(y)=0.16y , is used to convert
timurjin [86]

They probably want 880 pesos, since they asked you do intermediate rounding

but a more accurate answer would be
883.20 pesos

To combine the functions, you'd substitute in 2.76r for y in 0.16y. This would give you 0.16(2.76r), which simplifies to 0.4416r, but they want you round this to the nearest hundredth, so its really 0.44r.  Substitute in the 2000 for r and you get 0.44 * 2000 which is 880 pesos

domain: all real numbers (-∞,∞)

range: y ≤ 64

Step-by-step explanation:

since the domain is arn,

and range is the coordinates

coordniate (top or bottom-most point)

downward facing so the top

(2, 64)

since it is downward facing we use ≤ instead of ≥

y value is 64 (just as x is 2)

your answer is y ≤ 64

hope this helps:)
