To raise a function up by k units, add k to the whole function
f(x) is 2 units lower than g(x)
so -2 was added
k=-2
Answer:
no it is not the same because you get different answers
Answer:
thanks again man!!!! wooo
According to the definition, is a parabola is in the standard form of (x-h)^2<span>=4p(y-k), then the directrix is y=k-p. In this case, the parabola function is x^2=8y, so h=0, p=8/4=2, k=0. Plug the values of h, p, k, into y=k-p, the directrix is y=-2.</span>
