What is the inverse of the function f(x) = 2x – 10?
h(x) = 2x – 5
h(x) = 2x + 5
h(x) = one-halfx – 5
h(x) = one-halfx + 5

Step-by-step explanation:

You are given the function . To find the inverse function do such steps:

1. Rewrite the function f(x) as

2. Express x in terms of y:

3. Change x into y and y into x:

Now, the inverse function is

Option D.

Step-by-step explanation:

The given function is

We need to find the inverse of the function f(x).

Step 1 : Substitute f(x)=y.

Step 2: Interchange x and y.

Step 3: Isolate variable y.

Step 4: Substitute y=h(x).

The inverse of the function f(x) is .

Therefore, the correct option is D.

.25

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
