f(x)= -x^2+2x+5. Identify the vertex and intercept(s)
V=(-b/2a,f(-b/2a))=(2,f(2))=(2,5)
x-intercepts: x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ =x+=+%28-2+%2B-+sqrt%28+2%5E2-4%2A%28-1%29%2A5+%29%29%2F%282%2A%28-1%29%29+ =x+=+%28-2+%2B-+sqrt%2824%29%29%2F%28-2%29+
y-intercepts: y=f(0)=5
