We have that the data have a high point at the start (4). Then, it drops to a lowest point (3)  and then it increases again. Hence, an exponential fit is a bad idea; exponential functions are always increasing. The same applies to square root functions, they are always decreasing or increasing and they do not have up and downs.
A quadratic function is the most appropriate function to model the data. While it is true that also cubic functions can act like this, the simplest choice is quadratic functions; they have a lowest dip and then they increase on either side of the dip, just like the data.
The correct answer is d.

Answer:

This is clearly a quadratic equation because when you graph it, you get the parabola shape.

A car traveled 88 km in 1 hour, 90 km in the next 2 hours, and then 76 km in 1 hour before reaching its destination. what was th
luda_lava [24]

The formula for Average speed = \frac{Total Distance}{Total Time}

The car travels 80 km in 1 hour.

Then the car travels 90 km in 2 hours.

And finally the car travels 76 km in 1 hour

So the total distance covered by the car = 80 + 90 + 76 = 246 km

The total time taken to cover this distance = 1 + 2 + 1 = 4 hours.

So average speed = \frac{246}{4}= 61.5

The average speed of the car is 61.5 km / h

the price of an item has increased 15% since last year. However l a person can buy the item for a 25%employee discount. The empl
Fiesta28 [93]

Let us assume last year the price of the item = $x.

After increase in price by 15% the new price = x + 15% of x = x+ 0.15x = 1.15x.

There is a 25% discount for employee.

25% of 1.15x = 0.25 × 1.15x = 0.2875 x.

Price after discount = 1.15x - 0.2875 x = 0.8625x.

The employee pays $172.50.

Therefore,

0.8625x = 172.50.

Dividing both sides by 0.08625.

\frac{0.8625x }{ 0.8625} =\frac{172.50}{0.8625}

<h3>x=200.</h3><h3>Therefore, last year the price was $200.</h3>
