Solve the following equations simultaneously.
First solve for $x$x.
Find the value of $y$y at the point of intersection where $x=3$x=3.
Find the value of $y$y at the point of intersection where $x=-7$x=−7.
Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) =g(x); find the solutions approximately. ^Combine polynomial, rational, radical, absolute value, and exponential functions
