Answer:
y=4(x−2)^2−16
y=(x+11)^2-50
Step-by-step explanation:
Vertex form is y = a(x – h)^2 + k, where (h, k) is the vertex.
Standard for is Ax + By = C
simply rewrite the equations using the formulas
Answer:
x = -71/38
Step-by-step explanation:
y=x^2-16x
y=x^2+22x+71
x^2-16x = x^2 + 22x + 71
- 38x = 71
x = -71/38
