Hey there! :)

Answer:

First option: As x⇒ ∞ f(x) ⇒ -∞. As x⇒ -∞ f(x) ⇒ ∞.

Step-by-step explanation:

Rearrange the equation:

f(x) = -x³ - 2x² + 1

This is a negative cubic function. The function decreases over the interval

(-∞, ∞). Therefore:

As x⇒ ∞ f(x) ⇒ -∞.

As x⇒ -∞ f(x) ⇒ ∞.

This is the first option.

How many students were surveyed about their mode of transportation to school?

AlekseyPX

Answer:

Total number of students surveyed about their mode of transportation to school is 400.

Step-by-step explanation:

Here, given student who uses car as their mode of transport = 120 students

We have to find the total number of students who are surveyed.

Also, since complete circle represents 100% of data,

Total students who uses at least one mode of transport out of foot, bicycle, bus or car let it be x students.

Total percentage of students that uses bus, bicycle and on foot = (20 +15+35)% = 70%

Thus, percentage of students that uses car = 100 - 70 = 30%

Thus, 30 % of total students = 120

Mathematically, 30% of x = 120

Solving for x, we get,

$\frac{30}{100} \times x=120$

$\Rightarrow x=120 \times \frac{100}{30}$

$\Rightarrow x=400$

Thus, total number of students surveyed about their mode of transportation to school is 400.
