The work is equivalent to the dot product of the two vectors.
The equation that does not assign one value to y is and the points that do not represent a function is (c)
<h3>The equation that does not assign one value to y</h3>
To do this, we simply make y the subject of formula.
So, we have:
Simplify
Subtract 5/y from both sides
Rewrite as:
This means that the value of x is 0 irrespective of the value of y
Hence, the equation that does not assign one value to y is
<h3>The points that do not represent a function</h3>
For a set of point to represent a function, the points must represent a one-to-one or many-to-one relationship.
From the list of options, option (3) represents a one-to-many relationship.
This is so because one x value has 3 y values
Hence, the points that do not represent a function is (c)
