Function notation just replaces $y$ with $f(x)$.

Like in:

$y = 2x + 3$

Function notation will be:

$f(x) = 2x + 3$

Is there an equation you're trying to find function notation to?

Linear models are a part of everyday life, but many times they are not easily visible. They can be easily related to our life experiences. Read each of the three scenarios below to see how linear models show up in our lives and how we can use them to make decisions. Answer the related questions.

    Marco and his two younger sisters would like to purchase a silver charm bracelet for their mother’s birthday. They went to the mall and found what they were looking for at Store A. In Store A, the bracelet without charms costs $85 and each charm costs $15.

        Use function notation that models the total price of the bracelet and how that price is based on the number of charms. Explain the reasoning behind your equation.
        What would be a reasonable domain for this function based on this scenario? Explain why this is a proper domain.
        If Marco and his sisters have saved $250, make a graph to show all of the charms they could purchase with a bracelet if they had saved between $85 and $250.

Yeah, so you just replace $y$ with $f(x)$.

You would write the equation: $y = 85 + 15x$, so what would the function notation be?

f(x)=85+15x
