use a graphing calculator to approximate the vertex of the graph of the parabola defined by the following equation.
y=x^2+x+6

a. (0.5, -5.75)
b. (-0.5, 5.75)
c. (-0.5, 6)
d. (0.5, 5.75)

5050 i think

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
