What is the best approximation for the relative maximum of the polynomial function graphed below

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

answer: hence, function will be

explanation:

since we have given that

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
