    a) y = -4(x + 2)2 + 2 b) y = -4(x - 2)2 + 2 c) y = 4(x - 2)2 - 2 d) y = 4(x + 2)2 + 2

    because x+2 means your function is appearing 2 values earlier for x... in other words the base function shifted 2 left

    Not sure if you care to know but a quadratic equation has the form y=A(x-s)^2+t If A is negative that means the graph will be a frown if its positive then the graph will be a smile If Its (x-s) that means the graph has been shifted to the right s units and if its (x+s) the means the graph has been shifted left s units +t means the graph has moved up t units and -t the graph has been moved down t units
