An example of quadratic equation with this behavior is:
Which is sketched at the end of this answer.
A quadratic equation has the format:
It's roots are given by:
The number of roots depends on the discriminant 
, that is:
- If
, it has two different real roots. - If
, it has one real root. - If
, it has no real roots.
In this problem, it will have only positive y-values if: and 
Thus, an example is:

Answer:
Which is the equation of a parabola with focus (-5, 3) and vertex (-5, 6)?
Focus and Vertex are both on x = –5, so that’s the Axis of Symmetry.
Distance from Vertex to Focus is p = 3-6 = –3.
4p(y-k) = (x-h)^2
4(–3)(y–6) = (x-(-5))^2
–12(y–6) = (x+5)^2
y = (–1/12)(x+5)^2 + 6 <== Answer
Distance from Vertex to Directrix is –p = 3.
Directrix is y = 6+3 = 9.
Step-by-step explanation:
In expanded form, it would be 9*10 + 5*1 + 4 * 0.1 + 1 * 0.01 + 7 * 0.001. Hope this helps!
Answer:
56/45 or 1 11/45
Step-by-step explanation:
change to improper fractions and multiply the first by the reciprocal of the second
÷ 
= · 
= 
45 goes into 56 1 time with a remainder of 11
