help as soon as possible : what would the standard form be for this equation? f(x) = 3(x-1)^2+24

    The standard form would be: f(x)=ax^2+bx+c To make your parabola similar to that standard equation, you then need to simplify f(x) = 3(x-1)^2+24.

    f(x) = 3(x-1)(x-1)^2+24 is that how its supposed to start? ( iwasnt too sure )

    not quite inside the brackets is a perfect square so it becomes \[f(x) = 3(x^2 -2x +1) + 24\] just distribute and collect like terms

    f(x) = 3x^2 - 6x + 3 + 24

    could you help me with one more? Using complete sentences, explain how to find the average rate of change for f(x) from x = 4 to x = 7. Basically you just plug x into the function and solve from there right? ( ill give you another medal on someone elses post )

    well you need to plug them in and find f(4) and f(7) then jus find the slope between the ordered pairs (4, f(4)) and (7, f(7)) hope it helps
