Let f(x) = x2 − 16. Find f−1(x)

Yanka [14]

Answer:

$f^{-1}(x)=\pm\sqrt{x+16}$

Step-by-step explanation:

$f(x)=x^2-16$

To find the inverse of this function, temporarily the f(x) with a y (or whatever else you want) and then solve for the x.

$y=x^2-16\\y+16=x^2\\x=\pm\sqrt{y+16}$

Now, you can swap the variables again and write the function.

$f^{-1}(x)=\pm\sqrt{x+16}$

Consider the inequality 4x – 3 ≥ 13. Select four x-values that make the inequality true.

Neporo4naja [7]

Answer:

Step-by-step explanation:

Here are some steps to help you

Step 1

4x-3≥13 We are going to be simplifying

Step 2

4x-3≥13 Add 3 to the sides

4x≥16

Step 3

4x≥16 Divide them sides by 4

x≥4

So therefore your answer is x≥4

Hope this helps
