document.write( "Question 515072: Suppose we describe an equation as equality between functions f(x) = g(x). How do we interpret solutions to equations graphically? Create an example to use in your explanation. What is a solution to an equation?\r
\n" );
document.write( "\n" );
document.write( "I know a \"solution\" to one equation means \"where does it cross the x-axis, if anywhere\". This mean what are the value(s) of x when y=0, since y=0 is the definition of the x-axis. Also a \"solution\" to 2 or more equations means where do they cross each other or where do they have the same value. I just unsure of how the equality between the two functions affects this? I'm just confused thanks for the help!

Algebra.Com's Answer #343693 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! You're not confused. If two functions have the \n" ); document.write( "same solution the graphs of those functions \n" ); document.write( "meet at the point of the solution. \n" ); document.write( "------------------------ \n" ); document.write( "y = 2x+3 \n" ); document.write( "y = x -4 \n" ); document.write( "--- \n" ); document.write( "2x+3 = x-4 \n" ); document.write( "x = -7 \n" ); document.write( "--- \n" ); document.write( "Solve for \"y\": \n" ); document.write( "y = x-4 \n" ); document.write( "y = -7-4 = -11 \n" ); document.write( "y = -11 \n" ); document.write( "Solution: (-7,-11) \n" ); document.write( " \n" ); document.write( "====================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "==================== \n" ); document.write( " |
