We have been given the steps to solve the equation as
Step 1: 2x = 18
Step 2: x = 18 − 2
Step 3: x = 16
There is an error in step 2.
We have
x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.
So we must divide both sides by 2.
Therefore, A is the correct option.
A) She did not divide 18 by 2.
Answer:
Step-by-step explanation:
Hello!
Considering the parent function, as the most simple function that preserves the definition. Let's take the function given:
To have the the parent function, we must find the parent one, let's call it by f(x).
This function satisfies the Domain of the given one, because the Domain is still and the range as well.
Check below a graphical approach of those. The upper one is g(x) and the lower f(x), its parent one.
