During the winter, the the low temperature outside is x degrees Celsius, the daily cost to heat a building can be determined using the function f(x) = 10(1.1) negative power of x. Find and interpret the given function values and determine an appropriate domain for the function. Can y’all pls help?? Been stuck on this for a while now.
If y’all can give the forest answers as well it would be great. <3

B

Step-by-step explanation:

Given

y = ax² + bx + c

• If a > 0 then parabola opens up

• If a < 0 then parabola opens down

If a = > 0 then parabola opens up not down

Thus B  is not true
