    (-3,-6) is a point on y=f(x) determine a point on the graph y=3 abs(f(x))+1

    is it

    (3,3)
    (3,19)
    (-3,3)
    (-3,19)

    how do u do this one?

    Is it (3,19)? I dont know am I supposed to keep the points negative or do i make them positive because of the absolute bars? If I keep the point -6 and multiply by 3 and add 1 I dont get any of these answers, SOMEONE PLZ HELP QUICK!!!!!!

    The answer is : (-3, 19)
    you give the x=-3 and you get the 19.

    .

    so basically this means that when you use the value x=-3, you get the value, y=-6. So if you look at this equation, y=3*abs(f(x)) + 1, you want to plug in the value of y when x is equal to -3.

    y= 3*abs(-6)+1 = 3*6+1 = 19.
    So when x=-3, y= 19
