Answer:
No.
Step-by-step explanation:
A function must past the Vertical Line Test. We know that our equation x² + y² = 5 is a circle, and so some x-values have the same y-values, etc. Since not every x-value has its own y-value, our equation is <em>not</em> a function.
We can see this using a graph:
Since the vertical line test passes 2 points with the same x-value, it is not a function.
To factor this you need values that add up to 2 and multiply to -15
So you get 5,-3 then you put it into your equation for you b value
X^2+5x-3x-15
Then you can factor by grouping
X(x+5)-3(x+5)
So your factors are
(X+5)(x-3)
