Answer:
- 3x² is a term in the numerator
- x + 1 is a common factor
- The denominator has 3 terms
Step-by-step explanation:
You can identify terms and count them before you start factoring. Doing so will identify 3x² as a term in the numerator, and will show you there are 3 terms in the denominator.
When you factor the expression, you get ...
This reveals a common factor of x+1.
So, the above three observations are true of this rational expression.
Answer:
f⁻¹(x) =
Explanation:
To get the inverse of a function, we have to follow these steps:
1- replace f(x) with y
2- swap the x and y variables
3- solve for y
4- replace y with f⁻¹(x)
Applying this to the given as follows:
f(x) =
Step 1: replace f(x) with y:
y =
Step 2: swap the x and y variables:
x =
Step 3: solve for y:
7x = 4y - 3
4y = 7x - 3
y =
Step 4: replace y with f⁻¹(x):
f⁻¹(x) =
