For the function f(x) = 3(x - 1)2 + 2, identify the vertex, domain, and range.

Question

For the function f(x) = 3(x − 1)2 + 2, identify the vertex, domain, and range.

Answer 1

In the function: f(x) = a(x - h)² + k, (h, k) is the vertex.

 

For the given function, (1, 2) is thew vertex.

The domain is all real numbers.

The range is {y | y ≥ 1}.
