Question

Help plz fan and medal

Answer 1

The function f(x) = −x2 + 50x − 264 models the profit, in dollars, a yoga studio makes for selling monthly memberships, where x is the number of memberships sold and f(x) is the amount of profit.

Part A: Determine the vertex. What does this calculation mean in the context of the problem? (5 points)
Part B: Determine the x-intercepts. What do these values mean in the context of the problem? (5 points)

Answer 2

I only need help on Part B

Answer 5

really :/ no one :/

Answer 6

Sorry, I forgot how to do this. I'd help you if I could.

Answer 7

Oh ok thanks man ._.

Answer 8

Alright dude :P

Answer 9

\[ f(x) = −x^2 + 50x − 264 \]
this is a parabola with the shape of \( \cap\), so it has a peak (called the vertex)
the x value of the vertex is found using
\[ x= \frac{-b}{2a} \]
where a and b are defined by matching your parabola with
\[ y=a x^2 + bx + c \]

Answer 10

@DarkMoonZ Sorry, I forgot that this was a quadratic function. Ugh. I did know how to do this. Sorry, cuz i saw x2 i assumed it wasn't

Answer 11

Oh ok then lol

Answer 12

Part B in the context of the problem x-intercepts means when y = 0
the subscriptions sold when no profit is made
