2x^2-3x-2=0 \\
2x^2-4x+x-2=0 \\
2x(x-2)+1(x-2)=0 \\
(2x+1)(x-2)=0 \\
2x+1=0 \ \lor \ x-2=0 \\
2x=-1 \ \lor \ x=2 \\
x=-\frac{1}{2} \ \lor \ x=2 \\
\boxed{x=-\frac{1}{2} \hbox{ or } x=2}

2x² - 3x - 2 = 0
x = <u>-(-3) +/- √((-3)² - 4(2)(-2))</u>
                     2(2)
x = <u>3 +/- √(9 + 16)</u>
                 4
x = <u>3 +/- √(25)
</u>             4<u>
</u>x = <u>3 +/- 5
</u>          4
x = <u>3 + 5</u>  or  x = <u>3 - 5</u>
         4                   4
x = <u>8</u>             x = <u>-2</u>
      4                    4
x = 2             x = ⁻¹/₂

What is the range of the relation in the table below?
aksik [14]

Range is the set of all values which the given function can output. The correct option is A.

<h3>What is domain and range of a function?</h3>
  • Domain is the set of values for which the given function is defined.
  • Range is the set of all values which the given function can output.

Since y is the output for the given function, and the only outputs that can be seen for the function are 0, 2, and 4. Therefore, the range of the function is {0,2,4}.

Hence, the correct option is A.
