Use the following graph B=0.003x3+0.13x2-1.2x+18.6 Approximate the average BMI for 10-year-old males; for 16-year-old males. Can you show how to plug values? Solution There is two ways to do this. We can look at the graph where it says Age and go to the line between 8 and 12. This is 10 then move straight up to the point this line hits the graph. This is the BMI for 10 year olds. It is slightly above 16. We can find the exact number by pluging our value into x in our equationB=0.003x^3+0.13x^2-1.2x+18.6 B=0.003(10)^3+0.13(10)^2-1.2(10)+18.6=22.6 For 16 year olds we do the same thing and get a BMI a little above 20 B=0.003(16)^3+0.13(16)^2-1.2(16)+18.6=44.968 I hope this helps .

1. Use the following graph B=0.003x3+0.13x2-1.2x+18.6
Approximate the average BMI for 10-year-old males; for 16-year-old males.
Can you show how to plug values?
Solution
There is two ways to do this. We can look at the graph where it says Age and go to the line
between 8 and 12. This is 10 then move straight up to the point this line hits the graph. This is
the BMI for 10 year olds. It is slightly above 16. We can find the exact number by pluging our
value into x in our equationB=0.003x^3+0.13x^2-1.2x+18.6 B=0.003(10)^3+0.13(10)^2-
1.2(10)+18.6=22.6 For 16 year olds we do the same thing and get a BMI a little above 20
B=0.003(16)^3+0.13(16)^2-1.2(16)+18.6=44.968 I hope this helps
