3. write the equation of the line of symmetry for the function f(x) = -x - 4x-8.
a. x = -2
f(x)=x² – qx-8
b. x = -4
c. y = -2
d. y = -4

Which function can be used to model the monthly profit for x trinkets produced? f(x) = –4(x – 50)(x – 250) f(x) = (x – 50)(x – 250) f(x) = 28(x + 50)(x + 250) f(x) = (x + 50)(x + 250)
