Question

jaime bought a jar of 50 vitamins. his two children each take one vitamin each day. the number of vitamins left in the jar after x days is represented by the function f (x) =50 - 2x. Graph the function and explain what each intercept represents

Answer 1

Explanation:

f(x) = 50 - 2x

x = 0 when the vitamins are bought and none have been taken 9 that is day 0).

So the intercept on the y axis 50 - 2(0) = 50 represents this situation ( day = 0 and number of vitamins = 50).

When all the vitamins have been taken f(x) = 0 so we have

50 - 2(25) = 0 This is the intercept on the x axis ( x = 25 days).
