Step-by-step explanation:

Given : Function .

To find : Which function is a quadratic function.

Solution : We have given that functions .

Quadratic function: A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers.

We can see from given options

y = -2x² - x in form of f(x) = ax² + bx + c,

Where, a = -2 , b = -1 c = 0

Therefore,  y = -2x² - x is quadratic function.

The sum of 9 and the product of a number and 5 is 24.
evablogger [386]

Answer:

The number would be 3.

Step-by-step explanation:

This problem can be written as

5x + 9 = 24

So to solve it, you have to isolate x:

5x + 9 = 24

5x + 9 - 9 = 24 - 9

5x = 15

5x÷5 = 15÷5

x = 3

Check:

5(3) + 9

= 15 + 9

= 24

fomenos

Answer:

The function rule be 100 × x

The independent variables i.e. (2, 3, and 4) are considered to be the domain

The dependent variable (200,300,400) are considered to be the range

Step-by-step explanation:

The computation is shown below:

As we know that

1 m = 100 cm

So

2 m = 200 cm

3 m = 300 cm

4 m = 400 cm

The function rule be 100 × x

The independent variables i.e. (2, 3, and 4) are considered to be the domain

The dependent variable (200,300,400) are considered to be the range
