Can anybody tell me the answers to number 1, 2 & 3 ???!!!!

Problem 1

Domain = {-1, -3, 2, 1}

Range = {5, 0, 2}

The domain is the set of possible inputs and the range is the set of possible outputs. This is a function because each input goes to exactly one output.

========================================

Problem 2

This is a function as well. We do not have any input going to multiple outputs.

Domain = {-2, -3, 5}

Range = {6, 7, 8}

========================================

Problem 3

This is not a function. The input -4 goes to more than one output (outputs 3 and -1 at the same time)

Domain = {-4, -2, 0}

Range = {3, -1, -2, 4}

Need help on math You have a meal at a restaurant. The sale tax is 8% . You leave a tip for the waitress that is 20% of the pret

DerKrebs [107]

Answer: $18

Step-by-step explanation:

Let x= Pretax price of the meal.

Given: Sales tax = 8%

Tip percent = 20%

As per given ,

Amount spent = ( Pretax price) + (Sales tax ) of (Pretax price) + (Tip percent)of (Pretax price)

= x+ 8% of x + 20% of x

= x +0.08+0.20x

= 1.28x

∵ Amount spent = $23.04

So,

$1.28x=23.04\\\\\Rightarrow\ x=\dfrac{23.04}{1.28}\\\\\Rightarrow\ x=18$

Hence, the pretax price of the meal= $18.
