Answer:

B. The square root of 16 is 4., and 4 is a whole number. A whole number is a part of the rational family.

Step-by-step explanation:

Remember: A rational number is any number that can be written into a fraction. Such as integers.

A is incorrect because 15 is not a whole numer, and it's decimals are not repeating with a pattern or terminating.

B is correct because the square root of 16, which is 4, is a whole number.

C is incorrect because 21 is not a whole numer, and it's decimals are not repeating with a pattern or terminating.

D is incorrect because 22 is not a whole numer, and it's decimals are not repeating with a pattern or terminating.

Given a quadratic function in vertex form:
Alja [10]

Answer:

See below

Step-by-step explanation:

<u>Part A</u>

A vertical stretch takes place when a\cdot f(x) given that  |a| > 1

<u>Part B</u>

A vertical compression takes place when a\cdot f(x) given that 0 < |a| < 1

<u>Part C</u>

A vertical stretch is different than a horizontal compression:

  • In a vertical stretch, the input stays the same, but the output is multiplied by the scale factor
  • In a horizontal compression, the output stays the same, but the input is multiplied by the scale factor

<u>Part D</u>

A reflection across the x-axis means that the output, our y-variable, is the opposite sign. This means that all values of a must be negative such that a\cdot f(x) as mentioned in parts A and B. Also, in part C, since our scale factor is negative, the output is the only one being multiplied by the scale factor.
