Answer:
Refer graph attached below
Step-by-step explanation:
Given equation [tex]x^2-4=5[/tex]
We have to Solve the given equation [tex]x^2-4=5[/tex] graphically.
We first solve the given equation [tex]x^2-4=5[/tex]
Consider the given equation [tex]x^2-4=5[/tex]
Adding 4 both sides, we have
[tex]\Rightarrow x^2-4+4=5+4[/tex]
Simplify, we get,
[tex]\Rightarrow x^2=9[/tex]
[tex]\Rightarrow x^2-9=0[/tex]
To plot the graph let [tex]x^2-9=y[/tex] be the equation
It will be a parabola with vertex (0,9).
