for my homework I have to graph 4 equations:
1. y=1/4x^2+3x-3
2. y=-x^2+7x-2
3. y<x^2+7x+6
4. y<*-1/3x^2+4x+5/2
[<* means greater than OR equal to. I just don't know how to put the line under it]
we are allowed to do them on a calculator. but since I don't have the type of calculator that we need at home, I used an online calculator. graphing #1 and 2 was easy, but I can't find a calculator where you can put in y< or y>. if you know any web sites please share. thank you.
[and please don't tell me that I'm lying.. we're just learning how to do it on a calculator so I don't have to do it on my own]
I understand that you are looking for a website where you can graph equations with inequalities like y < or y >. Unfortunately, I cannot provide a specific website recommendation as I cannot browse the internet. However, I can explain the process of graphing inequality equations on a calculator.
To graph equations with inequalities, you can use graphing calculators that support these features, such as TI-84, Desmos, or GeoGebra. Here's a general step-by-step guide to graphing inequalities on a calculator:
1. Open the graphing calculator application or website.
2. Enter the equation into the calculator's input area. For example, for the equation y < x^2 + 7x + 6, you would need to input it as y < x^2 + 7x + 6.
3. Check the calculator's syntax for correctly inputting the inequality symbol. Some calculators might use a specific syntax, such as "<" or "≤" for y < or y ≤. Refer to the calculator's user manual or guide to find the appropriate symbol.
4. After entering the equation with the inequality symbol, press the "Graph" or "Draw" button to graph the equation.
5. The calculator should display the graph of the equation on its screen, showing the portion of the graph that satisfies the inequality condition.
By following these steps, you should be able to graph equations with inequalities on a calculator, helping you to solve your homework. Remember to refer to your calculator's instructions or online resources specific to your calculator model for further guidance.
