Question

What is function notation

Answer 1

Function notation is a way of writing a function. f(x) is written instead of using y. For example, f(x) = 6x + 2

Have a good day!

Answer 2

Explanation: Function notation is the equation $y=3x-4$ can be written using function notation.

Example: $2r=s+1$

Consider the function represented by the equation $2r=s+1$. Write the equation in function notation, where s is the independent variable.

$2r=s+1$

$\frac{2r}{2}= \frac{s}{2}+ \frac{1}{2}$

$r=\frac{1}{2}s+ \frac{1}{2}$

$\boxed{f(s)=1/2s+1/2}$

Hope this helps!

Thanks!

Have a great day!
