Answer:
See below (I hope this helps!)
Step-by-step explanation:
The vertical line test is a test used to determine whether a relation is also a function. It is done by inserting several vertical lines that intersect the relation. If a vertical line intersects the relation at multiple point, then it is not a function. If every single inserted vertical line intersects the relation at only one point, then the relation is a function.
You would have to replace f(x) with zero and use quadratic formula
f(x)=x^2-5x+5
0=x^2-5x+5
=(-b+-√b^2-4ac)/2a
=(5+-√25-4(1)(5))/2
=(5+-√5)/2
x=(5+√5)/2 or x=(5-√5)/2
Both x values are completely applicable in the equation.
