The price of a bag of popcorn at a basketball game increased from $3.10 to $3.75. The concession stand sold 290 bags of popcorn. With the price increase, how much more money did the concession stand earn on the bags of popcorn?

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
