Answer:
y-intercept: 
axis of symmetry: 
vertex: 
Step-by-step explanation:
To find the y-intercept, set x = 0 and solve for y.
I am assuming f(x) = y



The y-intercept of the equation is y = 0.
Now, for the axis of symmetry, you need the equation 
In an equation.. 
In this case, there is only an a, so plug in the values into the equation.


The axis of symmetry is x = 0.
To find the vertex, change the format of the equation from standard form to vertex form.
Vertex form: 
The vertex is 


The vertex in this case is (0,0).
Graphing makes things a lot easier. If you can graph it, all you have to do is look at the graph and the answers are all there!

Answer:
15
Step-by-step explanation:
The hypotenuse of a triangle is a² + b² = c².
12² + 9² = c²
144 + 81 = 225
√225 = 15
