Answer:
The graph has only one x-intercept
Step-by-step explanation:
we have

we know that
The discriminant of a quadratic equation of the form 
 
 
is equal to
 
in this problem we have

so

substitute
 
 
 
The discriminant is zero
That means ----> The quadratic equation has one real solution
The graph has only one x-intercept
