Answer:
The scale factor of the following dilation is, 0.5
Step-by-step explanation:
The rule of dilation with scale factor k is given by:
As per the statement:
Given the following dilation:
(10, 0) → (5, 0) .....[1]
We have to find the scale factor.
Using the above rule we have;
Now compare this with equation [1] we have;
(10k, 0) = (5, 0)
⇒10k = 5
After solving we get;
Therefore, the scale factor of the following dilation is, 0.5
If the equation is then the domain is the set of all real numbers.
We can replace x with any real number and compute to get some real number output for y. There are no division by zero restrictions to worry about, or issues with taking a square root of a negative number (since this isn't really a square root function).
The cube root of a negative number is negative. For example, because (-4)^3 = (-4)*(-4)*(-4) = -64.
In interval notation, the domain would be written as to indicate the entire real number line.
