Yakvenalex [24]4 years ago
5 0

Answer:

The set of output values are (1,3,11,17) as Range

Step-by-step explanation:

Given function is f(x)=2x-3 and domain  is (-1,0,4,7)

Function is given that taking set of input values from domain and give out set of output values.

For x=(-1)

f(x)=2x-3

f(-1)=2(-1)+3=(-2)+3=1

For x=0

f(x)=2x-3

f(0)=2(0)+3=3

For x=4

f(x)=2x-3

f(4)=2(4)+3=-8+3=11

For x=7

f(x)=2x-3

f(7)=2(7)+3=14+3=17

Thus,

The set of output values are (1,3,11,17) as Range

What else would you need to measure the area of something
kumpel [21]

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

A bond that appreciates 4% per year will be worth $146 in five years. find the current value.
Anastasy [175]

Answer:

$120

Step-by-step explanation:

Let the initial value of bond be $X

The future value of any bond is calculated by formula

FV= PV(1+r)^n

where

  • FV is future value of bond
  • PV is present value of bond
  • r is the rate that at which value of bond appreciate
  • n is the number of years of maturity

In the problem given

FV= $146

r = 4% = 0.04 (dividing 4 by 100 we get 0.04)

n = 5

substituting these value in formula

146 = X(1+0.04)^5\\=> X = 146/1.04^5\\=> X = 120

PV =$X = $120

Hence current value of bond is $120.

Determine if the following relation represents a function or not.
artcher [175]

Answer:

It is a function.

Step-by-step explanation:

Functions are relations in which one domain value is assigned to exactly one range value. The x-value must not repeat in the relation set for it to be a function.

{(2,3), (4,3), (6,3), (5,9), (3,9)}

There are no repeating x-values given.

The relation should be a function.

Hope this helps.
