Question

An appliance manufacturer estimates that the profit y (in dolars) generated by producing x cooktops per month is given by the equation

y= 10x + 0.5x^2 - 0.001x^3 - 5000

where 0 ¡Ü x ¡Ü 450.
Graph the equation.

I punched in the equation and I didn't get anything. I don't know what I should do with 0 ¡Ü x ¡Ü 450

Answer 1

First, the inequality converted to Western encoding is:
where 0 ≤ x ≤ 450.

Then you need to understand that not all calculators have the same features. So it would help if you identify the make and model of your graphics calculators if you are looking into the operation of the calculator. In general, graphing software allow the limits of the independent variable to graph, which is precisely the "0 ≤ x ≤ 450" requirement.

Answer 2

oops the 0 <or= x <or= 450

I don't know how to make the less than equal sign on my keyboard.

Answer 3

my calculator is TI - 83 Plus

Answer 4

Unfortunately I don't have a TI-83plus. I hope someone who has one will be able to help you.

To type ≤ or ≥ you would type "& l e ;" and "& g e ;" respectively, without the double quotes and without the intevening spaces. Try it on your next post.
Don't forget to change the encoding back to Western-8859-1 before you do so. You probably have a default with another coding.
