Answer: the root of 145 so b
Step-by-step explanation:
Standard Form : f (x) = a(x - h)2 + k
Where in this equation (H,K) is the vortex of the parabola
<u>and there are four other ways to solving these quadratic</u>
1. Factoring
2. Completing the square
3. Your quadratic formula ( f (x) = a(x - h)2 + k )
4. Graphing
Well to find the range, you need to take the highest number and subtract the lowest from it:
3 - -97
3 + 97
100
Range is always positive
