Answer:
- f(x) vertex is a minimum
- g(x) vertex is a maximum
Step-by-step explanation:
The reasoning is the same in each case: the sign of the coefficient of the squared term indicates the direction the parabola opens. If it opens upward, the vertex is a minimum; if it opens downward, the vertex is a maximum.
f(x) -- the sign of the squared term is positive, so the vertex is a <em>minimum</em>.
g(x) -- the sign of the squared term is negative, so the vertex is a <em>maximum</em>.
Answer:
5280 ft
Step-by-step explanation:
1 mile = 5280 ft
350 x 15 = 5,250
5, 250 divided by 1000 is 5.25
15% = 5.25
if the price was marked up 15% the price would be
$ 360.25 >> 350 + 5.25
if the price was marked down 15% , the price will be $ 344.75
