Hello!
The answer is:
The function intercepts de x-axis at "x" equal to 1.631.
Why?
To find the x-intercept of the function, we need to make f(x) or "y" equal to 0, and then, isolate "x".
So, isolating we have:

Hence, we have that the function intercepts de x-axis at "x" equal to 1.631.
Have a nice day!
