The equation that describes how the parent function, y = x³, is vertically stretched by a factor of 4 is y = 4x³.
<h3>We can find how the equation is vertically stretched below:</h3>
When an equation is vertically stretched, it means that the parent equation has been multiplied by a number that is more than one.
This means that the equation is multiplied by some factor.
It is given that we should describe how the parent function is vertically stretched by a factor of 4.
The parent function is given as y = x³.
Since the equation is said to be vertically stretched by a factor of 4, we must multiply the parent equation by 4 to stretch it.
Therefore, we have found the equation that describes how the parent function, y = x³, is vertically stretched by a factor of 4 to be y = 4x³.

None of the options give the same fees for a session of x hours.
Given,
x + 20/2 = 3x
when two tutoring services with different rate plans charge the same fees for a session of x hours.
<h3>What is arithmetic?</h3>
In mathematics, it deals with numbers of operations according to the statements.
x + 20/2 = 3x
x + 10 = 3x
A) x= 10
10 + 10 = 3*10
20 ≠ 30
B) x=4
4 + 10 = 3 * 4
14 ≠ 12
C) x= -14
-14 + 10 = 3 * -14
-4 ≠ 42
D) x=-17
- 17 + 10 = 3 * - 17
-7 ≠ -51
Here, none of the options give the same fees for a session of x hours.
Thus, none of the options give the same fees for a session of x hours.

Answer:
Yes, this is a right triangle
Step-by-step explanation:
Plug the values into the pythagorean thm.
1.5^2 + 2^2 = 2.5^2
2.25+4=6.25
6.25=6.25
