The axis of symmetry for the function f(x) = –2x2 + 4x + 1 is the line x = 1. where is the vertex of the function located? (0, 1) (1, 3) (1, 7) (2, 1)

Step-by-step explanation:

If the axis of symmetry is located at x = 1, that is the h value of our vertex (h, k).  If we know h, all we have to do to find k is sub the value for h into the quadratic and evaluate.

so f(1) = 3.  Your choice is (1, 3)

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
