Which of the following is the equation of the quadratic function with f(1) = 0 and f(5) = -6, an axis of symmetry at x = 5, and a vertex that is a maximum?
A f(x) = {(x - 1)(x – 4)
B f(x) = -1 (x - 1)(x – 4)
c f(x) = -(x + 1)(x + 4)
D f(x) = {(x + 1)(x+4)
please helpp!!!

hi, i am not sure about this one but i think its d,

hope this !

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
