Answer 1

i can't help your math problem just gave me a headache :) sry

Answer 2

f(x)=-2x^2+x+16, place the parabola into standard form to find max/min

Answer 3

f(x)= -2 (x-1/4) ^2 + 127/8

Answer 4

your maximum occurs at 127/8 and there is no minimum for your function

Answer 5

how can there be no minimuum? :S
