Answer: The answer is f(x) = - 2x²+12x-22.
Step-by-step explanation: We are given to write the function describing a parabola with vertex (3, -4) and passing through the point (5, -12).
We know that the standard form of a parabola with vertex (h, k) is given by
Here (h, k) = (3, -4), so we have
Also, the parabola is passing through the point (5, -12), so
Substituting the value of 'a' above in equation (I), we have
Thus, the answer is f(x) = - 2x²+12x-22..
Answer:
Step-by-step explanation:
To evaluate:
Since the fractions have a common denominator, so we can simply add the numerators keeping the denominator as it is.

This question is pretty much asking: Write a story that can be represented by the equation y=1.25x.
So, how about this one: Lily's mom tells Lily to clean up her toys. Lily puts toys away at a rate of one toy per every 1.25 seconds.
That's it, simple as that :P
(Sorry if it wasn't too helpful.)
