The expression 16 = 4x-2 is exponential equation that is option (b)
According to the expression, there is only one variable that is x .
So, let us look into the options :
Option A is almost correct as exponential expression is just a way to write powers in short form.
Option C is incorrect as exponential function is a function which involves a relationship between an independent variable x and dependent variable y. Examples - y = 2 +3
Option D is also incorrect as exponential inequality is a function involving expression which can be solved for all x satisfying the inequality. For example, 641/3 > 2
Option B is correct option as exponential equation is an equation that can be solved for all x values satisfying the equation. For examples, 16 = 4x-2
Hence option B that is exponential equation is the correct option.
