Find the range for the given domain: {-2, -1, and 0} and the function is y= 3x^2
likoan [24]

Answer:

  {0, 3, 12}

Step-by-step explanation:

Put the domain values in the function and evaluate. The result is the range values.

  y = 3{-2, -1, 0}^2 = 3{4, 1, 0} = {12, 3, 0}

For the given domain, the range is {0, 3, 12}.

_____

<em>Additional comment</em>

Neither the domain nor range values need to be put in any particular order. However, it is often convenient for them to be arranged from least to greatest.

A metalworker has a metal alloy that is 15% copper and another alloy that is 75% copper. How many kilograms of each alloy should
attashe74 [19]
X - the mass of the first alloy (15%)
y - the mass of the second alloy (75%)

x kg of the first alloy contains 15%x=0.15x=(15/100)x=(3/20)x kg of copper
y kg of the second alloy contains 75%y=0.75y=(75/100)y=(3/4)y kg of copper
90 kg of a 51% copper alloy contains 51%*90=0.51*90=45.9 kg of copper

x+y=90 \\&#10;\frac{3}{20}x+\frac{3}{4}y=45.9 \ \ \ |\times (-\frac{4}{3}) \\ \\&#10;x+y=90 \\&#10;\underline{-\frac{1}{5}x-y=-61.2} \\&#10;x-\frac{1}{5}x=90-61.2 \\&#10;\frac{4}{5}x=28.8 \ \ \ |\times \frac{5}{4} \\&#10;x=36 \\ \\&#10;36+y=90 \\&#10;y=90-36 \\&#10;y=54

The metal worker should combine 36 kg of the 15% copper alloy and 54 kg of the 75% copper alloy to create 90 kilograms of a 51% copper alloy.
