Math Problem Statement
Find the inverse of the function. y= x+8 Write your answer in the form a(bx+c)2+d, where a, b, c, and d are constants. Enter the domain of the inverse in the form: x≤# or x≥#. Simplify any fractions.
Solution
Let's find the inverse of the function .
Step 1: Switch and
To find the inverse of a function, we switch and , then solve for :
Step 2: Solve for
Isolate :
Step 3: Express the inverse in the required form
We need to express the inverse function in the form . However, the given function is linear, not quadratic. Thus, rewriting it in quadratic form as requested is impossible since the inverse is simply a line. Therefore, the inverse function is:
Step 4: Domain of the inverse
Since there are no restrictions on in the original function, the domain of the inverse function is all real numbers. So, the domain can be written as .
However, since you asked for the domain in a specific form, we can write: which encompasses all real numbers.
