Am I right? I tried my best on it I just need someone to check over it! :)

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12

Which is the graph of this function 3 square root of x plus one if

Will give brainliest b. describe the function over each part of its domain. state whether it is constant, increasing, or decreasing, and state the slope over each part.
