How do you solve: f(x) = -x2e-x<br> +2xe-x , finding the zero's of f.
Maksim231197 [3]

Answer:

0 and 2

Step-by-step explanation:

f(x) = -x^2e^{-x}+2xe^{-x}

To find zeros set f(x)=0  and solve for x

0 = -x^2e^{-x}+2xe^{-x}

0 = -e^{-x}(x^2-2x)

now factor out x

0 = -xe^{-x}(x-2)

set each factor =0 and solve for x

x=0

-e^{-x}=0 no solution for x

x-2=0, x=2

zeros of f  are 0 and 2

Lin’s father is paying for a $20 meal.
timofeeve [1]
$15.81

15% of $20 is $3 so subtract that from $20 and u get $17.
Then 7% of $17 is $1.19 so subtract that from $17 and you get $15.81, which is the amount Lin’s father would pay for the meal in the end.
