On a coordinate plane, a curved line with a minimum value of (negative 1, negative 2), crosses the x-axis at (negative 2, 0) and
Oduvanchick [21]

Given:

A curved line with a minimum value of (-1,-2), crosses the x-axis at (-2, 0) and the y-axis at (0, 0).

To find:

x-intercepts of the function.

Solution:

The curved line passes through the points (-1,-2), (-2,0) and (0,0).

We know that, y-coordinate is zero at x-intercepts.

From the given points, only (-2,0) and (0,0) have 0 as y-coordinate.

So, x-intercepts of the function are (-2,0) and (0,0).

Therefore, the correct options are 1 and 3.

INSERT TWO RATIONAL NUMBERS BETWEEN 2 AND 3. How to find them?
Kay [80]
There are an infinite number of them.
Here are a few:

2.1
2.2
2.3
2.3000000001
2.30000000000000006
2.5
2.00009
.
.
etc.

How to find them:

You probably never heard this before, but I'll bet
you'll remember it from now on:

<em>ANY number that you can write down on paper completely, </em><em>using digits
and a decimal point if you need it but no symbols, is a rational number.</em>

If you can write it down completely without any 'comments', then it's rational.

What’s the amplitude and the period of this function?
Iteru [2.4K]

The amplitude and the period of the function are 3 and 2, respectively.

<h3>What are the amplitude and the period of a sinusoidal function?</h3>

Sinusoidal functions are periodic bounded functions whose form is described below:

y = A · sin (2π · t / T + Ф) + y'

Where:

  • y' - Midpoint
  • A - Amplitude
  • t - Time
  • Ф - Phase
  • T - Period

The period is the horizontal distance between two consecutive peaks or two consecutive bottoms and the amplitude is equal to the half of the distance between a peak and a consecutive bottom. Hence, the amplitude and the period are, respectively:

Amplitude

A = 0.5 · [2 - (- 4)]

A = 3

Period

T = 2 · [0.75 - (- 0.25)]

T = 2
