Question

suppose that x and y vary inversely and x=1 when y=12. write a function that models the inverse variation. graph the function and find y when x=5

Answer 1

y=12/x

Explanation:

if y=12, and x=1 so

general formula y=12/x

for x=5 , y=12/5=2.4

you can graph by ploting points such as (1,12), (5, 2.4),...
