Find the percent of change.

The original cost was $50 and the new cost is $60.

Increase of 20%

Increase of 10%

Increase of 16.67%

Decrease of 10%

Increase of 20%

Step-by-step explanation:

percent change = (new value - old value)/(old value) * 100%

Here, the new value is $60, and the old value is $50.

percent change = ($60 - $50)/($50) * 100%

percent change = ($10)/($50) * 100%

percent change = 1/5 * 100% = 0.2 * 100%

percent change = 20%

Since the percent change is positive, it is a percent increase.

Increase of 20%

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
