Question

Select the correct answer. Which equation represents a parabola that opens upward, has a minimum value of 3, and has an axis of symmetry at x = 3? A. f(x) = (x − 3)2 + 3 B. f(x) = (x − 3)2 − 6 C. f(x) = (x + 3)2 + 3 D. f(x) = (x + 3)2 − 6

Answer 1

Answer:

  A.  f(x) = (x − 3)^2 + 3

Step-by-step explanation:

For vertex (h, k), the equation is ...

  y = (x -h)^2 +k

For the given vertex of (3, 3), the equation is ...

  y = (x -3)^2 +3 . . . . . matches choice A

Answer 2

Answer:

A -y = (x -3)^2 +3 . . . .
