Solve the non linear equation x^2=3x+4 graphically using a calculator, Write the equations of the graphs you used to find the solution. I got this question wrong what would be my Y1= and Y2= equations. Not sure what I'm doing wrong but whenever I have an x^2 I get them wrong.
I cannot post any graph.
x^2 - 3x - 4 = 0
(x - 4)(x + 1) = 0
x = 4 or -1
I hope this helps.
To solve the non-linear equation x^2 = 3x + 4 graphically using a calculator, you need to rewrite the equation in the form y = f(x), where y is the dependent variable and x is the independent variable.
To do this, subtract 3x and 4 from both sides of the equation:
x^2 - 3x - 4 = 0
Now, rearrange the equation to get y = f(x):
y = x^2 - 3x - 4
Using a graphing calculator, you would typically enter the equation for y into the calculator as Y1, and you would graph it.
Now, to find the equations of the graphs you used to find the solution, let's assume you used Y1 and Y2 equations. Since there is only one equation given (y = x^2 - 3x - 4), it seems you might have made a mistake in your question.
If you could provide more information or clarify your question, I would be happy to help further.
