F(x) = 2x^2 + 4x - 6 be any quadratic function then i. Express f(x)in to the form of a(x - h)^2 + k
ii. Find the domain and range of f(x)
ili. Is f^-1(x)exist for the arbitrary domain of f(x)? write the suitable domain of f(x)where
the function f(x)is inversible.
iv)Sketch the curve of function f(x)for any arbitrary domain of f(x)
v. By the help of the graph, is f(x) injective or not? justify your answer.​
