What is function in math?
- A quantitative expression, rule, or law that describes the link between an independent variable and a dependent variable (the dependent variable).
- In mathematics, functions occur widespread, and they are essential for defining physical links in the sciences.
- A function is a type of rule that generates one output for a single output.
- This is represented by the equation y=x2. Any inputs for x result in an output for y. Given that x is the input value, we would state that y is a result of x.
- 5 × ( -5)⁻⁹ = -5 × 1/-5⁹ ⇒ 1/5⁸ = 1/390625
[ -5 × (-5)]⁻⁹ = [25]⁻⁹ = 1/25⁹ = 1/3814697265625
