    Question domain and range of function

    Assume that 'f' is the function defined on the interval [1,2] by the formula f(x) = 6x^2 + 6. Thus the domain of 'f' is the interval [1,2], the range of 'f' is the interval [12,30]. The graph of 'g' is obtained by shifting the graph of 'f' left 3 units.

    a)Give a formula for 'g'
    b)Find the domain of 'g'
    c)Find the range of 'g'

    Thank you!!!

    Re: domain and range of function

    a)When you shift left a units f(x) =6(x+a)^2 + 6
    and when you shift right a units f(x) =6(x-a)^2 + 6

    b) & c) trying draw the graph and see what you get....
