I need help pleaseee, someone

D

Step-by-step explanation:

Use the exponents to guide your answer. When we examine -∞, if the exponent is even, it will be a positive value. If it is odd, it will be a negative value. For positive ∞, it doesn't matter whether odd or even, the value will be positive.

So we automatically know as x approaches ∞, y has to be ∞.

But for -∞ it is trickier. You have 3x^6 and 75x^4 together that is positive, and 30x^5 that is negative. The first two is greater than 30x^5 overall, so as x approaches -∞, y also approaches ∞.

If you need a visual, this is what it looks like:

(D).

Step-by-step explanation:

f(x) = 3 + 30 + 75

Domain: - ∞ < x < ∞

Range: y ≥ 0

⇒ The correct answer is the last option.

x ----> - ∞ , y ----> ∞

x ----> ∞ , y ----> ∞

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
