Question

hich function in vertex form is equivalent to f(x) = x2 + 6x + 3? f(x) = (x + 3)2 + 3 f(x) = (x + 3)2 − 6 f(x) = (x + 6)2 + 3 f(x) = (x + 6)2 − 6

Answer 1

f(x) = (x + 3)2 − 6

You can find the vertex by looking for -b/2a which is equal to -3 and then finding the corresponding y value, which is -6. Then use those numbers in vertex form, which is what we see in the answer above.
