A company produces accessories for smart phones and tablets.
The profit on each smart phone case is $2 and
The profit on each tablet case is $3.

The company made a profit of $1,200 on the cases last month. The equation 2x + 3y = 1,200 represents the company's profit from cases last month,
…where x is the number of smart phone cases sold and y is the number of tablet cases sold.
3. Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.

Oh, remember we changed this graph to $y = -\dfrac{2}{3}x + 400$?

kidthatbro8 · Answer

yes.

igreen · Answer

Function notation is just changing y to f(x).

Can you do that?

igreen · Answer

For example

Function notation of $y = x + 3$ is $f(x) = x + 3$.

kidthatbro8 · Answer

would it be f(x) = −2/3x + 400?

kidthatbro8 · Answer

f(x) = -2/3x + 400, sorry, i don't know what went wrong up there.

igreen · Answer

Yep.
