    Please solve these!

    I'm really desperate!

    Graph this parabola

    x=y^2 and y=-(x-2)^2

    Write logbase2 64=6 as an exponential equation.

    x=y^2

    Set up a table of values for x and solve for y. Here are a few. Plot the points

    Code:
     
    x | y
    -----
    0 | 0
    4 | +/-2
    9 | +/-3
    16| +/-4
    The domain is all positive real numbers and zero. The parabola opens to the right with its vertex at (0, 0) and the x-axis is its axis of symmetry.

    y=-(x-2)^2

    Do the same thing here. Set up your table and plot some points

    Code:
     
    x  | y
    ------
    0  | -4
    1  | -1
    -1 | -9
    2  | 0
    -2 |-16
    3  | -1
    -3 |-25
    This parabola opens downward because a<0. The vertex is at (2, 0) and the y-intercept is -4


    \log_264=6 is the same as 2^6=64
