First, simplify the expression of the function
highlighting the perfect square:

Then find the vertwx of parabola. When x=2, f(2)=2 and the coordinates of the vertex are (2,2). The axis of symmetry passes through the vertex and is parallel to the y-axis. Therefore, its equation is x=2 (see attached graph for details).
Answer: x=2.

➷ First, just divide the numbers:
12/4 = 3
When dividing values with exponents, you have to subtract the exponents:
7 - 5 = 2
Therefore, your answer would be option B. 3b^2
