What is the inverse of the function f(x) = 2x – 10?

Lana71 [14]

Answer:

$h(x)=\dfrac{x}{2}+5$

Step-by-step explanation:

You are given the function $f(x)=2x-10$ . To find the inverse function $f^{-1}(x)$ do such steps:

1. Rewrite the function f(x) as

$y=2x-10$

2. Express x in terms of y:

$y+10=2x\\ \\x=\dfrac{y}{2}+5$

3. Change x into y and y into x:

$y=\dfrac{x}{2}+5$

Now, the inverse function is

$f^{-1}(x)=\dfrac{x}{2}+5$

The price of a pair of earrings is $22 but Priya buys them on sale for $13.20.

BARSIC [14]

Answer:

$8.80
40%

Step-by-step explanation:

The amount of the discount is the difference between the original price and the discounted price. That was ...

$22.00 -13.20 = $8.80

The percentage of the discount is the ratio of the amount of the discount to the original price. That was ...

8.80/22.00 × 100% = 40%

The price was discounted $8.80. That was a 40% discount.
