We need to figure out how to graph the equations with absolute value in a graphing calculator.
Let's see, how to graph the equation in a):
[tex]|x|=x^2+x-3[/tex]
One way of doing so is by using the functions:
[tex]\begin{gathered} f(x)=|x| \\ \\ g(x)=x^2+x-3 \end{gathered}[/tex]
Then, the points of intersection of those two functions will be the solution to:
[tex]\begin{gathered} f(x)=g(x) \\ \text{ or} \\ |x|=x^2+x-3 \end{gathered}[/tex]
It is also possible to write "y" instead of "f(x)" or "g(x)".
