An ice cream shop was doing research on its sales. The results showed that the relationship between the average

daily temperature in Fahrenheit, �, and the daily ice

cream profit in dollars, �, could be modeled by the

equation � = 17.6� − 721.6.

According to the model, which of the following

temperatures to the nearest tenth of a degree would

make the ice cream shop have a positive profit?

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

add 8+12 to get a simplified answer of 12r-20
