Wouldn’t it just be any number lower than 4.7?
The graph crosses the x axis where g(x) = 0 , so:-
x^2 - 5 = 0
x^2 = 5
x = sqrt5 or -sqrt5
so grapg corosses the x axis at (-sqrt5,0) and (sqrt5, 0)
{0,<span><span>2π</span>3</span>,<span><span>4π</span>3</span><span>} should be the answer?

X = 35
use the formula a^2 + b^2 = c^2 in order to find the hypotenuse, which is x.
21^2 + 28^2 = c^2
441 + 784 = c^2
1225 = c^2
35 = c
x = 35
