Answer:
x = 49
Step-by-step explanation:
1- Substitute g ( x ) = 0
Reduce
g ( x ) = - x 2/4 + 7
2- Move the variable to the left 
0 = - x 1/2 + 7
3- Simplify the equation
x 1/2 = 7
4- Simplify Evaluate 
( x 1/2 ) ² = 7²
5- Check the solution
x= 49
6- Simplify 
0= - 49 2/4 + 7
7- x = 49 is a solution
0 = 0
