In the real world, functions are mathematical representations of input-output situations. Example: Weekly salary is a function of the hourly pay rate and the number of hours worked.

Provide a unique example of a function and evaluate the function for a specific input.

Step-by-step explanation:

Given a utility function U(q) = -q²-4q+2 in this case, depending on demand (q), this is function because it is a relationship or correspondence between two magnitudes, so that each value of the first corresponds to a single value of the second (or none); for example to q=-2 U(q) = 6, this means that for a demand (-2) the utility will be maximum (6) , and to -∞<q<(-4-√24)/2 ∧  (-4+√24)/2<q<∞ the utility will be negative;  (-4-√24)/2<q< (-4+√24)/2 the utility will be positive and q=(-4-√24)/2 ∧ q= (-4+√24)/2 there will be no utility

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
