Answer:
4) There are two solutions 3 and -3
Step-by-step explanation:
Here, the given equation,
Let,
And,
By graphing f(x) and g(x),
We found that the intersection point of f(x) and g(x) are (-3,5) and (3,5),
Thus, the solution of the given equation = x-coordinates of the intersection points of f(x) and g(x),
Hence, the solution of the given equation are -3 and 3.
Option 4 is correct.
