add an image, and i will answer

step-by-step explanation:

may i see the picture? it would a lot, xox

answer: you need the equation in the question so i can answer it

step-by-step explanation:

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
